Improving DECT performance with band-pass equalization

Band-pass equalization for the Digital Enhanced Cordless Telecommunications (DECT) is described. Assuming the GFSK DECT signal is sampled at the Nyquist rate, 3.456 Msps, practical methods for the estimation of the modulation parameters are developed that use only the first 32 bits of the DECT slot. Total complexity can be assumed by modern signal processors. After equalization our simulation results show that for a two-ray Rayleigh RF channel the system is operational up to a 600 nsec delay spread, independent of the value of modulation index (within the DECT range).
