Abstract :
This paper discusses an adaptive modulation/coding (AMC) strategy based on frequency-domain channel statistical information for OFDM systems in a frequency-selective fading environment. The proposed approach is based on the fact that the statistical properties of a time-varying channel vary very slowly with time and thus it is possible to obtain reliable knowledge at the transmitter. A programmable Reed-Solomon RS (n,k) code used with an adaptive multi-level modulation scheme is proposed as an illustrative example. Derivations of the frequency-domain channel statistical properties and performance of the proposed technique are presented along with illustrative results.
