中文说明：资源描述这是一个加入了LDPC编码的IDMA系统。LDPC采用PEG算法，码率可控，解码算法采用的是Log-Domino SPA Decoder。其余相关参数有：BPSK调制，AWGN噪声。最后可以得到相关系统的误码率曲线图。
English Description：
Application backgroundThis is a join LDPC encoding IDMA system. LDPC using PEG algorithm, the rate control, the decoding algorithm is used SPA Decoder Log-Domino. The remaining parameters are: BPSK modulation, AWGN noise. At the end of the system, the error rate of the system can be obtained.
