Abstract
Channel estimation is one of the key techniques in orthogonal frequency division multiplexing (OFDM). In this paper, we propose a data-aided time domain channel estimation method by solving a system of linear equations. To achieve good performance, we use genetic algorithm to find an optimized pilot. Simulation results in ZP-OFDM systems are given.
