As a new bandwidth-efficient coded modulation scheme, turbo trellis-coded-modulation ( TTCM) has recently received much attention in channel coding of digital communication systems due to its near capacity performance and high bandwidth-efficiency. Turbo网格编码调制技术(TTCM)在数字通信系统中引起人们浓厚的兴趣,因为这种将编码和调制结合在一起的新技术不仅有高的差错纠正能力,而且还具有很高的带宽利用率。
Bit-interleaved coded modulation with iterative decoding ( BICM-ID) is a spectral efficient coded modulation technique to improve the performance of digital communication systems. 采用迭代译码的比特交织编码调制(BICM-ID)系统是一种频谱利用率高、纠错性能好的数字通信系统。
