On the Compensation of RF Impairments with Multiple Antennas in SIMO OFDM Systems

Pierre-François Morlat, J. Perez1, Guillaume Villemaud2, Jacques Verdier1, Jean-Marie Gorce2

This paper provides an analysis of the impact of radio frequency (RF) front end impairments (I/Q gain and phase imbalance, phase noise, non-linear distortion and direct current offset) on the performance of a single input multiple output orthogonal frequency division multiplexing (SIMO OFDM) receiver. We developed a new estimation/compensation scheme to jointly compensate for the effect of multipath and RF non- idealities on baseband signals in the special case of Zero-IF receivers. Some first results illustrating this approach are presented for a 4 antenna 802.11 g receiver with the SMI algorithm and with or without IQ imbalance, as well as BER curves for different phase noise models.
