Analysis of 60 GHz band indoor wireless channels with channel configurations

Abstract

In this paper, 60 GHz indoor broadband wireless channels are measured with various configurations in a typical office environment. Measurements are taken at nine positions of the room and the base-station antenna is placed either at the center or at an edge of the measurement room, and the remote-station antenna is of either sharp beam or broad beam type. The RMS delay spread (RDS) and normalized received power (NRP) are estimated from the measurements. Statistical models of the 60 GHz indoor wireless channels are also presented with model parameters from the measured channel data based on the Saleh's (1987) indoor channel modeling method. Bit error rate (BER) simulations are performed using measured and simulated channel impulse responses with DQPSK-OFDM modulation, respectively. Using sharp beam antenna results in superior performances to using broad beam antenna in terms of both bit error rates (BER) and NRP penalty. Also, placing the base-station antenna at the center is superior to placing it at an edge in terms of BER and NRP.
