Diversity Performance of a Practical Non-Coherent Detect-and-Forward Receiver
—We propose a non-coherent receiver for the fixed detect-and-forward relay channel and derive a closed-form tight upper bound on its bit error probability in Rayleigh fading cha...

Non-Coherent Amplify-and-Forward Generalized Likelihood Ratio Test Receiver
Abstract—This paper proposes a simple non-coherent amplifyand-forward receiver for the relay channel and evaluates its diversity performance for Rayleigh fading channels. We use ...

Non-Coherent Detection for Amplify-and-Forward Relay Systems in a Rayleigh Fading Environment
— We consider about a multiple relay system operating under amplify-and-forward (AF) protocol and non-coherent modulation and demodulation. When the relays are under long-term po...

Closed-Loop Transmit Diversity with Imperfect Feedback
The closed-loop transmit diversity technique is used to improve the performance of the downlink channel in MIMO communication systems. In these closed-loop systems, feedback delay...

The performance of multi-user cooperative diversity in an asynchronous CDMA uplink
Abstract--This paper investigates the impact of interuser non-orthogonality and asynchronous communication on the information-outage probability performance of multi-user decode-an...
