An LDPC Decoder with SNR Information for IEEE 802.11n

碩士 === 國立交通大學 === 電控工程研究所 === 100 === In this thesis, we implemented an architecture of LDPC decoder for IEEE 802.11n with code rate is 1/2 and code length is 648. In order to reduce the area, we use partial parallel method. We use the SNR information with Min-Sum-Correct algorithm to improve the BE...
