SIMPLE NONCOHERENT EQUALIZER FOR THE DECT SYSTEM

A non-coherent equaliser structure suitable for DECT-type systems is i ntroduced which performs equalisation at the output of a differential detector. It employs a two-state Viterbi algorithm using a simple chan nel estimation process. Performance assessments are presented which su ggest that the new receiver can yield significant improvements with re spect to standard non-coherent receivers in dispersive channels. At th e same time, unlike coherent equaliser structures, it remains largely unaffected by both modulation index drifts and frequency offsets.
