Title: Combining and Pre-equalization Algorithms for Complementary Coded CDMA Systems

Speaker: Prof. Hsiao-Hwa Chen

Affiliation: National Cheng Kung University

Abstract:
   Complementary coded CDMA (CC-CDMA) offers a much better correlation properties than a traditional CDMA system. A CC-CDMA system offers unique interference resistant performance, which is extremely important to improve the overall performance of CDMA wireless communication applications. However, the ideal interference resistance property of a CC-CDMA system is impaired by frequency selective fading due to variable gains in different sub-channels that are used to send different element codes of a complementary code for a user. This work will address the issues in detail by introducing several counter-measures to mitigate the impact of frequency selective fading on the performance of a CC-CDMA system. In particular, the effectiveness of several combining and pre-equalization techniques will be investigated to demonstrate the diversity gains and detection efficiency achievable in a CC-CDMA system under various channel scenarios.
