基于自适应滤波的信道估计改进算法与实现
Channel estimation improved algorithm based on adaptive filtering and its implementation
摘要
Abstract
In order to adapt to the OFDM communication system application under the condition of wireless channel,an adaptive filtering technology based on SNR estimation is used to perform the smoothing filtering for the initial channel estimation result,reduce the effect of noise on the estimation result,and improve bit error rate performance of the channel estimation algo?rithm. The design realized on FPGA makes the occupation of the lookup table and trigger resource become 6 167 and 3 853 re?spectively,and total equivalent gate area to be decreased by 8.34%.关键词
