Abstract
Turbo trellis coded modulation (TTCM) invented by Patrick Robertson adapted the bandwidth efficiency of TCM and iterative decoding of turbo codes and presented better performance without bandwidth expansion [P. Robertson et al., 1996]. But TTCM has a difficulty of implementing a hardware owing to decoder complexity. So, we need efficient scheduling and date storage management. In order to solve this essential problem, we propose a novel TTCM decoder using sliding window technique by using trace back technique, which is popular for realizing long path memories for Virterbi decoders [A.J. Viterbi, Feb. 1998].
Patrick Robertson发明的Turbo栅格编码调制(TTCM)利用了TCM的带宽效率和Turbo码的迭代解码，在不扩展带宽的情况下具有更好的性能[P]。Robertson et al.， 1996]。但由于解码器的复杂性，TTCM在硬件实现上存在困难。因此，我们需要高效的调度和数据存储管理。为了解决这一关键问题，我们提出了一种新的TTCM解码器，该解码器采用滑动窗口技术，利用回溯技术实现Virterbi解码器的长路径存储器[a . j .]Viterbi, Feb. 1998]。
