A novel design paradigm for wireless data delivery involves use of a scheduler at a base station to schedule users awaiting transmission and send downlink data to these users with all available cell power. This is unlike previous systems that share the available downlink power between users and trade off interference with capacity. The concept is used in 3G wireless standards like 1xEVDO and HSDPA. The scheduler is designed to exploit the peaks in channels seen by different users and transmit data to the user that can support the best rate. In contrast, antenna diversity, where multiple antennas are deployed at the receiver or transmitter; has the effect of improving received signal fidelity by averaging the channel variation. In this thesis, we evaluate the joint effect of user diversity and antenna diversity for various scheduling algorithms. The system is first studied with a single user to calculate theoretical throughput values. A loaded system is then simulated and throughput trends are plotted for each user. Total system capacity is evaluated in terms of served bytes for various combinations of scheduling algorithm, diversity type and channel quality. Multi-user scheduling diversity is studied using the same system simulation model via Tomlinson Harashima precoding. Results are generated for various cell powers. Single-user and multi-user scheduling cases are compared to understand the pros and cons of each approach. / Master of Science

Yes / In this study, we aim to develop an understanding of the similarity between migration and expatriation, identify both as elements in diversity, and draw attention to the additional layer of ethnic diversity created by the high number of top management expatriates in some Nigerian subsidiaries of transnational corporations. Using the qualitative research design, we thematically analysed data from semistructured interviews with six indigenous managers in four transnational corporations. We found a significant number of expatriate managers in two subsidiaries and a lack of diversity management framework to address the new layer of diversity as reflected in the unequal treatment of indigenous managers. We conclude that migration and expatriation are similar and could be better managed through effective diversity management framework.

This is an examination of how conjugality acts as an access point for Canadian citizenship. The conjugal family unit — married or common-law — continues to be privileged in Canadian law and policy; this is especially evident in immigration policy and practice. Family class immigration continues to be a steady source of immigrants for Canada, spousal/partner sponsorship being the primary type of family reunification. In order to control access, a strict understanding of conjugality is used to distinguish between legitimate and illegitimate families. When it comes to family class immigration, it is not simply a case of individuals sponsoring individuals; it is about the state producing and maintaining the ideal family unit through the provision of citizenship. My analysis proceeds in two main parts. First, I engage with mainstream Canadian citizenship theory — focusing specifically on the work of Will Kymlicka and Rita Dhamoon — and analyze its focus on the individual citizen. Moreover, I examine how the state’s asymmetrical treatment of conjugality has created two versions of the conjugal family — the inside family (families within Canadian borders) and the outside family (families outside Canadian borders). Second, I explore the state’s reliance on conjugal relationships in their assessment of potential immigrants and refugees in three areas of immigration policy — the assessment of sexual minority refugee claimants, the assessment of common-law couples seeking sponsorship, and the government’s current crackdown on marriage fraud. Combined, these examples speak to the Canadian state’s vested interest in privileging the conjugal family unit; furthermore, they highlight how the inconsistent and often ambiguous treatment of conjugality undermines its effectiveness as the primary mode of identification in family class immigration. In summary, this dissertation integrates families into a body of scholarship that has ignored the role that one’s personal relationships plays in the provision of state access. / Thesis (Ph.D, Political Studies) -- Queen's University, 2013-03-06 20:33:38.518
