Abstract :
Bandwidth expanding signaling with quasi-orthogonal short codes where the bandwidth expansion factor N⩽8, is considered. The evaluation of the average probability of error over channels with multipath induced intersymbol interference (ISI) (which model broadband indoor and outdoor millimeter wave radio propagation) is presented, for two different receivers. Namely the rake receiver with equal gain combining and the postdetection integrator. Both BFSK modulation with noncoherent demodulation and DPSK modulation are analysed
