Abstract
In this paper, we face the problem of blind channel estimation in zero padding OFDM systems. Based on the assumption that the transmitted symbols are independent and identically distributed, we propose a blind adaptive estimation algorithm for minimum phase channels, based on Independent Component Analysis, that exploits the particular structure of the ZP-OFDM system model. Some included simulations show that this novel algorithm can yield comparable performance as the SVD methods with a reduced computational complexity.
