摘要
Abstract
In this paper, a new orthogonal frequency division multiplexing (OFDM) channel estimation was proposed. This method was an iterative channel estimation algorithm based on the least-squares criteria using superimposed pilot in time-domain, and the algorithm got effectively use of multiple OFDM symbols for joint channel estimation, and at the receiving end, according to the estimated channel information update real-time transmitted sequence, and then continue to correct channel information for feedback of iterative algorithm, the proposed scheme improved channel estimation performance greatly through computer simulation.关键词
