摘要

本文通过仿真分析了采用芯片级均衡器和turbo编码的高级3G (WCDMA)接收机中，由于信道交织器所对应的误码率(BER)和帧误码率(FER)所产生的交织增益。考虑瀑布区域。采用传统的RAKE接收机作为参考。多址干扰通常建模为加性高斯白噪声，通过严格按照标准生成其他用户的信号来模拟。对两种接收机(RAKE接收机和高级接收机)的仿真结果表明，信道交错可以显著提高性能。

FER and channel interleavers in 3G (WCDMA) systems using turbo-coding

In this paper the interleaving gain, due to the channel interleavers, corresponding to BER (bit error rate) and FER (frame error rate) in an advanced 3G (WCDMA) receiver, using chip level equalizer and turbo coding, is analyzed by simulation. The waterfall region is considered. The conventional RAKE receiver is used as a reference. MAI (multiple access interference), usually modelled as an additive white Gaussian noise, is simulated by generating signals of other users strictly according to the standards. The simulation results for both receivers (RAKE and advanced one) show that channel interleaves enhance performance considerably.
