A multiple access modulation technique that uses multilevel frequency shift keying (MFSK) to modulate frequency-hopped spread spectrum carriers has been examined for possible applications in satell

Consider M independent users, each user having his own transmit antenna, that transmit simultaneously to a receiver equipped with N antennas through a Rayleigh block-fading channel having a coheren

In this paper, the design of decision-feedback multiuser (DFM) receivers for asynchronous code-division multiple-access (CDMA) systems over a mismatched flat Rayleigh fading channel is studied, and

Demodulation and decoding for frequency-hopped spread-spectrum multiple-access (FH/SSMA) systems have been traditionally conducted by conventional single-user (noncollaborative) demodulation and er

We consider multicarrier multiple access architectures that are based on combining discrete multitone (DMT) or filtered multitone (FMT) modulation with multplexing of tones across users.

This paper describes the optimisation of a class of multiuser detectors for a return link multimedia LEO satellites constellation system.

We formulate the optimum multicarrier multiuser detector to be deployed in asynchronous multitone multiuser systems.

We present simulated error rate and code delay/amplitude tracking performance for two recently developed detectors: the adaptive whitened matched filter, and the quasi-synchronous decorrelator, Rap

We propose a generalized architecture for the phase shifter network in hybrid analog/digital beamforming (BF), which can provide flexible tradeoff between the performance and implementation complex

Based on the characteristics of interference seen by a user in a cellular network, we present a very simple multiuser transmission scheme.
