Receive “In General” for OFDM Signas in Memory Channels with Doppler Shift

The algorithm processing orthogonal frequency multiplexing (OFDM) signals in memory channels with Doppler shift is covered in the article. The offered algorithm is based on OFDM symbol sequence processing “in general” on dispersion interval with purpose of receiving maximum likelihood estimates of above sequence to get result of transferred QAM-symbols according to the classical scheme with usage of FFT. The statistical modeling of RGEWDM (reception in general with element-wise decision-making) algorithm processing OFDM-symbols was done using Jakes model of channel. This modeling was shown high characteristics of noise immunity in memory channels with Doppler shift.
