Abstract

Physical-layer analysis on millimeter-wave systems to date have used channels models reduced from measurements in static environments. This is because most millimeter-wave channel sounders take hours for a full channel sweep due to the slow mechanical rotation of single directional antennas. Rather, by using arrays of electronically-switched directional antennas, our state-of-the art 60- GHz channel sounder can take a full channel sweep in fractions of a millisecond. In order to provide more accurate analysis, we conducted an extensive channel measurement campaign including 325 distinct transmitter-receiver deployments in an indoor environment with pedestrian motion. The resultant channel model was used to analyze IEEE 802.11ay, the new standard for next-generation Wi- Fi operating in the unlicensed 60-GHz band expected for release in 2019. The standard is an amendment to its 802.11ad predecessor to include 8x8 single-user MIMO (amongst a flurry of other enhancements). The physical-layer analysis was based on an extension of the MATLAB® implementation of 802.11ay to incorporate a proposed scheme for 8x8 single-user MIMO tailored to the specific properties of the measured channel. The analysis resulted in bit-error-rate curves for various transceiver parameters, namely the number of RF chains, phased-array antenna dimension, and the modulation and coding schemes.
