超宽带无线通信中LDPC码硬件仿真实现

A Hardware Simulation Flat Implementation of Low Density Parity Check Code for UWB Communication

讨论了LDPC码在超宽带(UWB)无线通信中的应用及其硬件实现。首先讨论了译码初始化方法,并设计了硬件解码结构,然后在SystemGenerator环境中对整个译码算法进行了参数化的FPGA实现,最后在VC环境下构建了UWB系统LDPC码软硬件仿真平台,仿真表明改进的LDPC码比传统的LDPC码更能满足UWB通信需求。

In this paper, the advantages and decoding progress of LDPC code are described as well＂ as the initialization algorithm of the decoder in different environment. Then we discuss the deocde structure of hardware,at last the FPGA parameterization is implemented and the system performance is verified under the SystemGenerator and VC environment.
