摘要
讨论了在频率选择性衰落无线信道下WCDMA系统中的空时格型编码(STTC)性能。介绍了STTC系统模型,重点讨论了WCDMA下行链路STTC系统的几种接收机,通过仿真给出了STTC WCDMA系统在频率选择性衰落信道上的FER(误帧率)和BER(误比特率)性能。
The performance, of space time trellis coded (STTC) over frequency-selective fading wireless channel for WCDMA systems is analyzed. Various receiver structures of STTC system in WCDMA forward links are considered. The simulation results demonstrate performance of FER and BER for frequency selective fading channel in STTC WCDMA systems.
