Abstract :
In this paper, an autoregressive (AR) channel model for simulating frequency selective channels in synchronized orthogonal frequency division multiplexing (OFDM) systems is proposed. By frequency domain AR filtering, the number of Rayleigh processes for generating the channel frequency response (CFR) is reduced. Thus, this model is able to achieve a low complexity.
