Abstract :
A new expression for the bit error rate (BER) of DQPSK in slow Rayleigh fading with a space diversity receiver for the indoor MM-wave channel is derived. The space diversity receiver consists of a cascade arrangement of M-selection and L-maximal ratio combiners, allowing the use of a large number of antennas for performance improvement and combiners with a small number of inputs for low complexity. An efficient computation of the derived closed form error probability expression facilitates a judicious selection of M and L, given a required level of performance
