Performance Results of Two Iterative Receivers for Distributed MIMO OFDM With Large Doppler Deviations

This paper studies a distributed orthogonal frequency-division multiplexing (OFDM) system with multiple quasi-synchronous users, where different users may transmit different numbers of parallel data streams. The distinction from most existing work is that the multipath channels for different users have significantly different Doppler scales. Such a setting with two single-transmitter users was first studied in a recent publication by Tu et al....
