Cochannel interference cancellation by base station adaptive array in uncorrelated rayleigh fading channel

摘要

The interference cancellation characteristics of an adaptive array are discussed when the fading at each ele- ment is uncorrelated assuming low height base station. In this paper, we focus on the case that the number of antennas and interference waves is large. From the investigation of SINR characteristics we have found that when the average SNR is large, no diversity gain is obtained, but when the Average SNR is small, the diversity gain is increased. In the BER characteristics when the number of antennas is less Than 7, an increase in the number of antennas increase the Gain.
