The degree distribution of the LT code optimized for BEC, AWGN channel. The degree distribution optimized for differential channel is also given.

二进制删除信道(BEC)的simulink仿真，模型中加了AWGN信道，并采用了QPSK调制解调-binary earsure channel

着重对极化码编码时涉及的信道选择技术进行展开研究。在二进制删除信道(BEC)环境下,利用Bhattacharyya参数分别从信道转移概率和码长的两方面说明对信道选择的影响。(This paper focuses on the channel selection technology in polarization code coding. In the binary deleted channel (BEC) environment, Bhattacharyya parameters are u

实现了polar在BEC信道下的编译码，画出了误码率图像(The encoding and decoding of polar in BEC channel is realized, and the bit error rate image is drawn.)
