Upper Bounds on the Average BER of Adaptive Arrays in Fading Environments

摘要

This paper presents upper bounds on the av- erage bit error rate(BER) of coherent detection of PSK and differential detection of DPSKwith adaptive arrays in fading en- vironments. A model where a lineof sight (LOS) component and Rayleigh distributed scatteringcomponents arrive at a receiver with specific arrival angles is usedconsidering the correlation of signal between multiple antennas. Theupper bounds are ex- pressed in a simple matrix form using signal andinterference- plus-noise correlation matrices.
