摘要：To meet the higher data rate requirement of encoder, an encoder structure suitable for both two rates(1/2,2/3B) in WIMAX standard is proposed, c ombined with the method of Design Space Exploration. According to the quasi cyclic characteristics of sparse parity check matrix, the traditional RU algorithm is simplified and optimized to reduce the complexity of the system. Simultaneously we introduce a barrel shifter, and use the method that two rows of the base matrix be restored in one ROM to reduce resource consumption. The simulation results show that the encoder for two rates not only runs successfully, but also reduces the utilization of hardware resources. The encoder architecture has broad application prospects with high flexibility.
