Design and performance evaluation of 802.11ad phys in 60 GHz multipath fading channel

Abstract

IEEE 802.11ad is the new Wi-Fi standard operating at 60 GHz. This paper investigate the performance of specified modulation and coding schemes in additive white Gaussian noise channel and realistic 60 GHz band multipath fading channel. Three 802.11 ad physical layers, namely orthogonal frequency division multiplex physical layer, Single Carrier and Low Power Single carrier physical layer, are designed and evaluated in terms of bit error rate and packet error rate performances. Simulation results show that single carrier modes in most cases outperforms OFDM modes in LOS and NLOS scenarios. QAM based modulation schemes are sensitive to marginal channel conditions and provide poor performance in NLOS case, while BPSK and QPSK modulation schemes with low density parity coding are relatively more robust, and present a good choice at the cost of data rate reduction.
