Abstract

In this paper, we consider a three-node relay system with a hybrid relaying scheme, where the relay, based on its decoding status, switches between decode-and-forward (DF) and compress-and-forward (CF) adaptively. We propose according HARQ strategy and analyze its throughput performance. Then, we consider practical implementation issues by enhancing the ability of the feedback channel from the destination to the relay to convey a few extra bits (only 2 bits in this paper) and propose a modified HARQ scheme accordingly. The combined technique exhibits superior performance over direct transmission and conventional DF.

We noticed that in a relay system, the assumption of global Channel State Information (CSI) knowledge is unrealistic and normally, only the receiver but not the transmitter side has CSI knowledge. In this paper, we analyzed, with receive CSI, the ...
