【摘要】 本文提出一种利用FPGA实现IEEE802.16e标准的通信系统LDPC编译码方法。由于编码算法使用了线性复杂度编码,明显减少了资源占用量,提高了编码速度。并对标准中的码长为1536,码率为2/3的LDPC码进行FPGA的仿真,验证了所提方法的有效性和可实现性。更多还原

【Abstract】 Based on the definition of LDPC in 802.16 e standard, an encoder and decoder is designed for FPGA. The linear time encoding method is used in encoding scheme, it reduces the quantity of logic resource and improves the encoding speed. The paper implements FPGA simulation of code length 1536 and code rate 2/3 in IEEE 802.16 e standard. The simulation results verify the feasibility and the effectiveness of the proposed method.更多还原
