Performance Analysis of Space-Time Block Coded System over Frequency-Selective Fading Channels

Dian‐Wu Yue

Abstract

Space time block coding (STBC), due to its high diversity gain and simple coding and decoding method, has aroused general concern. However, it can only be used in frequency flat fading channels although actual channels are mostly frequency selective fading. This paper is concerned with two system schemes with STBC: OFDM-STBC and SC/FDE-STBC, which are suitable for frequency selective fading channels. Namely, the combinations of STBC with OFDM or SC/FDE are considered. By comparing and analyzing simulation results for the performance of OFDM-STBC and SC/FDE-STBC systems, it is concluded that SC/FDE-STBC is superior to OFDM-STBC. In addition, some meticulous observations of simulation results are given.
