Abstract

The impact of the number of cochannel interferers on the simulated performance of an adaptive antenna combiner is studied. Current simulation are conducted for time division multiple access (TDMA) narrowband transmission over Rayleigh fading channels with coherent QPSK signaling at 1.7 GHz. System performance in terms of bit error rate (BER) curves is presented for 1,2,3, and 8 equal-power cochannel interferers and compared to BER curves of no interference and no diversity. The effects of the average signal-to-interference ratio on the number of bit errors per block are presented
