Performance of non-coherent digital equalisers in DECT systems

The performance, in terms of bit error rate, of various data detectors at the output of a 1 bit differential demodulator for DECT receivers, is evaluated assuming static channels. The relevant result is that a one-tap decision feedback equaliser with an optimised threshold value yields a similar performance to the much more complex Viterbi algorithm. Moreover, in the presence of channels with a strong intersymbol interference, the decision feedback equaliser gains more than 2 dB in terms of SNR at BER 10³ with respect to the threshold detector
