Performance analysis of a joint space-time block codes and channel estimation scheme in DL-PUSC mode of mobile WiMAX

Abstract

Mobile WiMAX has emerged as a starting point of broadband mobile wireless era. Besides plenty of advantages over the prior systems, it also utilizes multiple-antenna techniques to improve the transmission quality. Although this approach has been intensively studied, there are just few published works taking into account channel estimation to obtain realistic performance. This paper studies a joint STBC and channel estimation scheme to investigate the performance of the DL-PUSC mobile WiMAX in various mobile channels. Simulation results show significant improvement, up to 8 dB gain for PER and system throughput is achieved when employing STBC. © Institute for Computer Science, Social-Informatics and Telecommunications Engineering 2009.
