Modified Matching Pursuit based channel estimation for ISDB-T

This paper demonstrates a new approach in reliable channel estimation for Integrated Services Digital Broadcasting Terrestrial (ISDB-T) using Modified Matching Pursuit Algorithm (MMP). The assumption is that the channel characteristic of the succeeding symbols does have correlation with the adjacent symbols. The Matching Pursuit (MP) is used first for solving the channel estimation of the first symbol, and then a proposed MMP is used for succeeding symbol based on the last estimate of the MP. The result of the simulation shows that the MMP was able to validate decent channel estimation with reduced computational cost.
