Performance Analysis of OFDM-IDMA System Based on QC-LDPC
To meet the need of high rate and high reliability for next generation of wireless mobile communication system ,in this paper,we designed a new communications system of OFDM-IDMA based on QC-LDPC. The performance under different coding rate,different length of frame is analyzed,and we also compared the performance with the system based on convolutional codes,the simulation results show that this new system can provide greater coding gain and better communications service,it is very suitable for highspeed data transmission and also has very farreaching significance for the future of digital communication systems.
