Abstract [en]

Experimental and simulation results on well-known co-operating relayingschemes such as: amplify-and-forward (AF), detect-and-forward (DF), co-operativemaximum-ratio combining (CMRC), and distributed space-time coding (DSTC) arepresented in this paper. A novel relaying scheme named “selection relaying” (SR), inwhich one of two relays are selected base on path-loss, is also tested.We also implement the modes “Selective” and “Antenna Diversity”. The “Selective”option is designed to avoid forwarding of erroneous frames.In our measurements, all co-operative relaying schemes above increase the coveragearea as compared with direct transmission. The features “Antenna diversity” and “Selective”improve the performance. Good performance is obtained with CMRC, DSTCand SR.
