Performance Analysis of Alamouti Coded OFDM Systems over Rayleigh Fading Channels Correlated in Space and Time
(Chapter; Peer reviewed, 2010)This paper deals with the performance analysis of Alamouti coded orthogonal frequency division multiplexing (OFDM) systems over time-varying multipath Rayleigh fading channels. In our analysis, we consider a physically ... -
Performance analysis of Alamouti-coded OFDM systems over spatio-temporally correlated underwater acoustic channels
(IEEE International Conference on Communications;2017, Journal article; Peer reviewed, 2017)In this paper, we analyze the performance of Alamouti-coded orthogonal frequency division multiplexing (OFDM) systems over time-varying underwater acoustic (UWA) channels. A realistic UWA channel model has been considered, ... -
Performance analysis of cooperative communication systems with imperfect channel estimation
(IEEE International Conference on Communications, Journal article; Peer reviewed, 2009)This paper investigates the effects of channel estimation errors on the symbol-error-rate (SER) performance of a cooperative communication system operating in an amplify-and- forward (AF) mode. A pilot symbol assisted ... -
Performance Analysis of M-Ary PSK Modulation Schemes over Multiple Double Rayleigh Fading Channels with EGC in Cooperative Networks
(Peer reviewed; Chapter, 2010)This article studies the performance of M-ary phase shift keying (PSK) modulation schemes over mobile-to-mobile (M2M) fading channels with equal gain combining (EGC) in cooperative networks. The frequency-nonselective M2M ... -
