In this paper, we show the effects of phase noise on the bit-error rate (BER) and average achievable rate per user performance in downlink multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) based amplify-and-forward (AF) relay systems. We derive the mathematical representation of the signal-to-interference-plus-noise ratio(More)
In this paper, we show the effect of phase noise on the bit-error rate performance in multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems based on IEEE 802.11ad standards. We consider two different systems; (1) a system which has multiple antennas with independent phase noise at transmit and receive side and (2) a(More)
In this paper, we propose a phase noise cancellation algorithm in MIMO-OFDM systems where each transmit (TX) and receive (RX) antenna is equipped with independent oscillator. Most of previous works have considered phase noise model only in SISO-OFDM or simplified phase noise model in MIMO systems assuming that each TX and RX end shares one local oscillator.(More)
