—This paper deals with the case of a high speed mobile receiver operating in an orthogonal-frequency-divisionmultiplexing (OFDM) communication system. Assuming the knowledge of d...
Abstract--For broadcast channels, a power allocation scheme is proposed to maximize the number of active receivers, for each of which, a minimum rate Rmin > 0 can be achieved. U...

Abstract— The so-called receiver multiuser diversity aided multistage minimum mean-square error multiuser detector (RMD/MS-MMSE MUD), which was proposed previously by the author,...
—In this paper, we examine the effects of imperfect channel estimation at the receiver and no channel knowledge at the transmitter on the capacity of the fading Costa’s channel...
— We consider the optimal amount of training for single-antenna Rayleigh flat fading channels with peak-powerlimited input. The receiver uses known training symbols to perform m...
