Pairs of Real Pilots Channel Estimation in OQAM/OFDM System Based on Compressed Sensing
摘要
Abstract
In OQAM/OFDM system,the pair of pilot channel estimation method has a bad channel estimation performance and easily influenced by noise,to solve this problem,pairs of real pilots (POP) channel estimation method based on compressed sensing (CS) is proposed.This method applies the CS technique to the POP channel estimation method,which transforms the conventional frequency domain channel estimation method into the time domain channel estimation.Through the compressed sensing technique reconstructing the time domain channel information,the pilots expense is reducted,spectral efficiency is improved and a highly accuracy channel estimation is obtained.Comparing with the traditional channel estimation method in OQAM/OFDM system,the simulation results validate that the new method can get a superior performance and higher channel estimation accuracy while using fewer pilot symbols.关键词
