摘　　要：SPW是进行通信系统建模与仿真的开发平台,具有非常强大的用户接口功能。多元域LDPC码是通信界研究的热点课题,较二进制LDPC码有更优的纠错性能。在研究多元域LDPC码编译码理论的基础上,介绍了SPW封装模块的步骤,开发了多元域LDPC码编译码模块,并将其嵌入SPW通信库。搭建了基于SPW的性能测试平台,在此基础上进行了计算机仿真。SPW is a platform for modelling and simulation communication systems, and it has very strong function for user interface. Q-LDPC code is a hot point of channel coding technology which error-correcting performance exceeds B-LDPC code. Based on research of Q-LDPC code theory, the processes of model exploration based on SPW were introduced. Here the models of Q-LDPC encoding and decoding were designed, which was added to the communication library of SPW. A performance simulating platform of SPW was established. A simulation based on this model was proposed.
