A Non-Blind Channel Estimation Algorithm for OFDM Systems with High Transmission Efficiency
摘要
Abstract
A non-blind channel estimation algorithm for orthogonal frequency division multiplexing (OFDM) systems in multipath channels was proposed. The known training sequences are inserted into period originally used for CP. Channel parameters are estimated in frequency domain based on the pilot analysis. Computer simulation shows that the performance of the proposed algorithm is nearly the same as that of the conventional one, but the transmission rate is increased about 20%. Therefore, the proposed algorithm has a wide application for high speed wireless communication systems.关键词
