The study of simulated test for punctured convolutional codes
缩短卷积码的仿真实验研究
Punctured convolutional codes
收缩卷积码
Second , this paper design the simulation scheme of bicm for comparing the performance over fading channel and awgn channel that combine 2 / 3 rate , 4 states punctured convolutional code with 8psk modulation , matching block interleave or random interleave , transform through rayleigh channel or awgn channel and use the way that combine coherent demodulation with viterbi decoding in receiver . design the scheme of bicm _ id that use the iterative decoding technique and the scheme of tcm for compare
为了验证bicm和bicm _ id在衰落信道和加性高斯白噪声信道( awgn )下的性能,设计了一个2 / 3码率, 4状态的凿孔卷积码经过块交织或随机交织,与8psk调制相结合,在rayleigh信道下或awgn信道下传输,接收端采用相干解调与维特比译码相结合的bicm方案,在接收端引入迭代反馈译码的bicm _ id方案,以及与之相比较的tcm方案。
