In this contribution, we investigate the performance of relay-aided downlink (DL) direct sequence code division multiple access (DS-CDMA) system with multi-user transmitter preprocessing (MUTP) based on vector quantized channel impulse responses (VQ-CIRs). Specifically, the CIRs are estimated with the aid of training-sequence based estimation technique at each of the relays. These estimated CIRs are...
In this article, we analyze the performance of a downlink (DL) direct sequence code division multiple access (DS-CDMA) system aided by cooperative diversity for the bad urban power-delay distribution pertaining to ITV-R. The considered DL system supports multiuser transmitter preprocessing (MUTP) to mitigate the DL multiuser interference (MUI) at the relay stations (RSs) and mobile stations (MSs)...
In this contribution, we investigate the performance of downlink (DL) direct sequence code division multiple access (DS-CDMA) system with multi-user transmitter preprocessing (MUTP) based on noisy feedback of vector quantized (VQ) channel impulse responses (CIRs). Specifically, in this contribution, the channel impulse responses required to conceive the preprocessing matrix are estimated at each of...
