The Performance Simulation of MIMO-OFDM System Based on QC-LDPC
Lin Wang · Modern Electronics Technique · 2007
Quasi Cyclic Low Density Parity Check(QC-LDPC) code ia an important branch of LDPC code research.It is a kind of constructed LDPC codes ,which check matrix H is constructed by quasi cyclic method.MIMO-OFDM is being pursued as a potential candidate for 4G mobile wireless system.In this paper,QC-LDPCcodes are combined with the MIMO-OFDM system.Simulations show that QC-LDPC code has as good error correction performance as random LDPC code and other good QC-LDPC code on frequency selective channels.
