We propose a new class of unitary space-time matrix constellations that have nonuniform error performance. Such codes are important for transmission o...

General Packet Radio Service (GPRS) provides packet switched data service for mobile users. However, the existing GPRS specification does not provide...

In this letter, we use the well-known Walsh-Hadamard codes to construct larger sets of linearly dependent codes such that their matrix of correlations...

Accurate detection and estimation of overlapping fading multipath components is vital for many communication systems, particularly for positioning tec...

In this letter we investigate adaptive minimum bit error rate (BER) decision feedback multiuser receivers for DS-CDMA systems in fast frequency select...
