摘　　要：TurboTCM作为一种不展宽带宽的编码调制方案,可以获得较高的误比特率(BER)性能,通常编码调制方案可以采用UP (UngerboeckPartitioning)和BP (BlockPartitioning)两种集分割方式,在不同的信道下这两种方案有不同的性能,而且帧长度对TurboTCM的性能也有很大的影响.比较了衰落信道下两种不同的集分割方式以及不同帧长度对TurboTCM性能的影响,以Rayleigh衰落下8ASK和8PSK调制为例进行了TurboTCM的性能分析。High BER (bit error rate) performance can be obtained by employing Turbo TCM as a kind of coded modulation scheme without losing bandwidth efficiency. Traditionally, there are two kinds of set partitioning strategies, UP (Ungerboeck Partitioning) and BP (Block Partitioning), with different performance in different channel, and the frame length also has great impact on the performance of Turbo TCM. We compare two different set partitioning strategyies of Turbo TCM in Rayleigh fading channels and evaluate the performance of Turbo TCM with two set partitioning strategies and different frame length over Rayleigh fading channels by the example of 8PSK and 8ASK modulation and get significant results.
