To fulfill future airport capacity requirements, the proposed data link has to be a high capacity, high rate data link. Air-ground data link system can be used in orthogonal frequency division multiplexing (OFDM) systems to improve communication quality and capacity. A channel estimation design method for OFDM system by using correlation of pilot sequences has been proposed in this paper. The main...
In this paper, we present an improved iterative interchannel interference (ICI) cancellation and signal detection technique for orthogonal frequency division multiplexing (OFDM) system on fast time-varying fading channel with nonintegral-delay. As a consequence of the time-varying channel, the orthogonality of subcarriers is destroyed, resulting in interchannel interference (ICI), which increases...
