Radio broadcasting, from its inception, was recognized as a medium with educational possibilities. The decision of the Privy Council in 1931 to vest control of broadcasting in the federal government, therefore, invited Dominion participation in radio education. With the establishment of the CBC, and the implication that it was to develop radio's educational potential, the possibility of having national radio education became more real. National radio education developed in response to four general forces. First, as the depression closed, the CBC was able to stabilize its financial situation, evolve a policy on controversial programming, establish co-operative relations with certain voluntary educational associations, and sponsor a national investigation into school broadcasting. Second, the arrival of the Second World War created a fervent nationalistic feeling and provided the conditions for an increase in the power of the federal government. The result was an interventionist-nationalist policy, on the part of the Dominion Government, which found cultural expression in national radio education schemes, such as "Young Canada Listens" and "Farm Radio Forum." The third force involved in the development of national radio education was related to a general programme shift in Canadian broadcasting from light entertainment to a more serious fare. Besides the use of more abstract content, this programme shift was characterized by the creation of radio programmes to suit specific audience groups, various attempts to overcome the passivity of the radio audience and the use of the radio as a medium for artistic and creative expression. The growth of national radio education in the early 1940's both reflected this general programme shift and provided another channel within which it could be conveyed. Finally, national radio education developed because of a desire, on the part of provincial educational authorities, to co-operate with a federal agency, the CBC, in the production of educational broadcasts. This desire to co-operate stemmed, in part, from a renewed sense of confidence in the national broadcasting authority and a wish to secure the educational benefits presented by the radio. Co-operation was achieved eventually on three levels of radio education - inter-provincial, Dominion-Provincial and international. The fruits of such co-operation in educational broadcasting were programmes, such as "Young Canada Listens," "Kindergarten of the Air," "National Farm Radio Forum," "Sports College" and "National Citizen's Forum." The CBC emerged from the 1940's as a national clearing house for Canadian education. Through its radio broadcasts, publications, and co-operative relations with provincial and voluntary educational organizations, the Corporation helped to provide Canadians with a national educational experience. The CBC also provided the Canadian Government with a useful instrument in international radio education affairs. Radio's role in education also became firmly established in the 1940’s. Broadcasting functioned as an educational aid and was to be integrated into the traditional learning situation. No new methodology or philosophy accompanied the radio into the classroom. True to an early prophecy, the radio had expanded the range of possible experiences available to the learner, but that was where its educational influence terminated. / Education, Faculty of / Graduate

Between 1927 and 1987, American broadcast regulators undertook a project for radio. The project pursued multiple goals: to allocate wavelengths, to hold stations accountable to the public interest, to restrict prejudicial content, to protect domestic wavelengths from international signal interference, to sustain these policies over time with the advent of new media, and to evangelize the American way of life abroad. The Federal Communications Commission (FCC) and the State Department, as the primary institutions responsible for developing this American system of radio, addressed several challenges. Domestically, the FCC resolved the free speech questions of the time by resisting government ownership of radio stations, but regulating the airwaves in the “public interest, convenience, and necessity.” Internationally, the State Department set up radio stations to broadcast around the world. Religion played a primary role in the aims of this project - domestically, that every listener would receive uplifting faith content and internationally, that the world would know of American religiosity. Public utility law precedent was influential on the 1927 Federal Radio Act and its implementation. The Commission treated radio as if it were a public utility. In this way, it ruled that the listener took precedence over the broadcaster - specifically that all listeners had a right to a well-rounded programming lineup, including religious content. As a result, the Commission favored variety stations over single-interest outlets in a series of rulings that hurt religious stations. The Commission preferred that listeners receive religious content from outlets offering a variety of programming. The Commission also worked to protect listeners’ religious sensibilities from attack, most notably during the surge of anti-Semitic populism in the 1930s. The FCC and the State Department worked together to protect American wavelength sovereignty in the 1930s and 1940s. The primary source of interference came from Mexican border stations. These signals created reception problems for American listeners of domestic stations; these particular stations were ones that the Commission had favored for laudable content, including religious programming. The border outlets also featured content the Commission deemed illicit, such as astrology and quack medicine. In the early Cold War, American international broadcasters fought the Soviet Union in a war of ideas. These broadcasters included the State Department-run Voice of America and the semi-public Radio Free Europe. In this ideological battle against Communism, America used religion to defend a liberal conception of a just society. Freedom of worship and God-given human rights were key components. Domestically, the FCC continued to regulate licensees in the public interest in the early Cold War period. For example, the Commission implemented the 1949 Fairness Doctrine, which mandated that stations not only cover critical issues, but present these issues with balance. By the late 1980s, the American system was collapsing. In 1987, as a sign of this breakdown, the Fairness Doctrine was repealed. This system had given broadcasting a liberal role in a century of totalitarian regimes - to defend free speech and uplift American society. Religion was a primary component of the system and served to encourage Americans to become more civil and ethically grounded citizens.

An analysis of the probability of error for an SCA based digital communication system is developed. QPSK modulation and the signal to noise ratio degradation due to the SCA transmission are analyzed to predict the performance of the system in terms of probability of error. The design and analysis of a QPSK model, a pseudorandom generator, and a pseudorandom correlator are also presented in this thesis.
