ERAM算法在瑞利衰落信道下的性能分析
Performance Analysis of ERAM Algorithm in Rayleigh Fading Channel
摘要
Abstract
For the poor Bit Error Ratio(BER) performances of Rate Adaptation in Mobile(RAM) environments algorithm in the Rayleigh fading channel, based on RAM, an improved rate adaptive algorithm, named Enhanced RAM(ERAM), is proposed. It adjusts Signal to Noise Ratio(SNR) forecasting mechanism according to the channel change, sets the throughput table initial value according to BER requirements, and uses the ACK frame to carry the next frame transmission rate, so the algorithm reacts to channel variations quickly. Simulation results show that the improved algorithm not only keep better throughput performance, but also can effectively improve the bit error rate performance in the rayleigh flat fading channel model.关键词
