摘要
提出了一种新的截短栅格编码调制方法,用于和RS码级联以克服汇聚噪声的影响。仿真表明,与一般的栅格编码调制相比,这种截短栅格编码调制纠错性能相差不多,但后者的编译码要简单许多,易于用硬件来实现。
In this paper a novel punctured trellis-coded modulation is put forwardwhich can be concatenated with RS code to overcome the effect of collective noise.Simulation result shows that the bit-error performance of punctured trellis-coded modulation is almost the same as ordinary trellis-coded modulation.While coding and de-coding algorithm of the latter is simpler and can be realized with hardware easily.
