Abstract

Abstract
In this paper an exact closed-form expression for the performance of the orthogonal
frequency-division multiplexing (OFDM) system over LEO satellite channel is derived
where each subcarrier is modulated by M-QAM. The effect of two channel parameters,
namely the mean delay spread and maximum Doppler shift, on the system performance
is investigated for a realistic wireless channel environment model.
