Abstract :
We describe the algorithms, implementation, and laboratory performance of a real-time four element adaptive antenna array testbed for the uplink of a 1.9 GHz IS-136 PCS base station. Using our enhanced direct matrix inversion algorithm, experimental results show nearly a 6 dB higher gain at a 10-2 bit error rate (BER) with four versus the typical two receive antennas and operation at close to a 10 -2 BER even with an interferer of equal strength to the desired signal at 60 mph fading rates, These results demonstrate the feasibility of using adaptive arrays to increase both the range and capacity of TDMA cellular systems
