碩士 / 國立交通大學 / 電子研究所 / 99 / In wireless communication, due to severe uncertainty and all sorts of interferences in practical transmission environments, generally preamble and pilot signals are designed and included in a wireless communication system to facilitate the system’s initial synchronization and later tracking operations. The preamble and pilot signals are known sequences to both transmitter and receiver during communication. Regardless of preamble or pilot signals, the receiver needs to “match” the received signals with the known preamble/pilot signals for the synchronization purpose. No matter what synchronization algorithm is adopted, such matching operation costs significant computational complexities.
Therefore, for long-term operation of a mobile device and environmental protection awareness, low-power consumption is a necessity. In addition to investigating “green” algorithms, we will investigate and design the low-complexity algorithms for wireless baseband preamble and pilot based signal processing, for achieving the low-complexity transmitter and receiver design. Besides, this thesis will also investigate the effects of the low-complexity algorithms on each functional block in the receiver for the tradeoff issue between the system performances and computational complexities. This thesis will specifically consider the application designs of LTE/LTE-A Standard, 802.16e/802.16m Standard. This thesis will conduct a comprehensive result of the tradeoff between the system performances and the complexities. For the system designer, this result also can provide a whole new breakthrough point for the next-generation wireless communication system.
