—In this contribution we investigate the bit-error-rate (BER) performance of a downlink direct-sequence code-division multiple-access (DS-CDMA) system, where a set of relays are ...
In ultra-wideband (UWB) communications, the typical signal propagation through dense multipath fading offers potentially very large multipath diversity, but at the same time compl...
Abstract--Assuming imperfect channel estimation, we propose an improved detector for orthogonal frequency-division multiplexing (OFDM) systems over a frequency-selective fading cha...
Transmission over wireless fading channels under quality of service (QoS) constraints is studied when only the receiver has channel side information. Being unaware of the channel c...
Abstract— A least-squares (LS) channel estimation (CE) technique for mobile OFDM communications over a rapidly timevarying frequency-selective fading channel is investigated in t...
