Theory of the performance of a DECT receiver in a multipath channel

The :performance of a digital enhanced cordless telecommunications (DECT) r eceiver in a multipath channel is studied; The following issues were invest igated: irreducible bit-error rate (BER) performance of the differentially coherent detector in Rayleigh and Rician channels; BER performance in the p resence of both the noise in the receiver and a multipath interference. The theoretical estimates of the irreducible error rate developed in the paper showed reasonable agreement with the data obtained from computer-based sim ulation of the DECT link through a Rayleigh multipath channel. The combined effect from receiver noise and multipath interference has been studied, an d asymptotic formulas for the total error probability have been developed. The results of calculating the error probabilities using these asymptotics demonstrate good agreement with measured data.
