摘　　要：SPW是一个先进的通信系统建模、仿真工具,它具有非常灵活的自定义模块能力。编织卷积码是一种高效的纠错编码,具有比Turbo码更强的纠错能力。在介绍了编织卷积码原理的基础上,将编织卷积码封装为自定义模块,并在SPW环境中对编织卷积码在AWGN信道下的性能进行了仿真,仿真结果表明编织卷积码的性能与系统帧长、编码器个数有较大的关系。Signal Processing Workstation （SPW） is an advanced tool for modeling and simulating communication systems, which has very flexible capacity for user-defined token. Woven Convolutional Codes （WCCs） is an effective error-correct code and performs better than that of Turbo codes. This paper designs user-defined token of WCCs on the basis of introducing the principle and simulates the performances of WCCs over AWGN in SPW environment respectively. The simulation results show that the performance of WCCs relate the frame length and the number of encoders.
