Performance of Relay-Aided DS-CDMA Downlink Systems Communicating over Nakagami-m Fading Channels
—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 ...

Effects of Non-Ideal Channel Feedback on Dual-Stream MIMO-OFDMA System Performance
— In this paper we analyze the downlink OFDMA system-level performances of a 2x2 dual-stream MIMO multiuser transmission scheme under the assumptions of partial and noisy channel...
