Abstract :
Most DECT radio receivers, up to now, have been analog and detection was via a limiter-discriminator. We present a receiver including an all-digital part after the analog differential detection scheme. The tasks of the digital signal processing unit are: (i) to give an estimate of both the optimum sampling phase and the non-linear channel coefficients, (ii) one-tap decision feedback (DF) equalizer, and (iii) evaluation of the approximate optimum bias level of the threshold detector. We consider static channels with impulse responses generated by the simulation program SIRCIM. For channels with large delay-spread, use of the optimum threshold together with the DF equalizer gains about 2 dB at a BER=10-3 with respect to a receiver without an equalizer
