Multiple-input multiple-output (MIMO) and cooperative communications have been attracted great attention for the improvements of communication capacity, power consumption, and transmission coverage. The conventional fixed relaying protocols, amplify-and-forward (AF) and decode-and-forward (DF), have their own advantages and disadvantages, i.e. AF performs better than DF for low signal-to-noise ratio...
Average symbol error rate performance of a dual-hop amplify-and-forward (AF) multi-relay cooperative communication system in Rician fading environment is investigated in the paper. We also derive the closed-form expressions for the probability density function (pdf) and the moment generating function (MGF) of bounded SNR with a maximal-ratio combing receiver at the destination terminal. The correctness...
In this paper, we consider the sensor network, where multiple sensors communicate with a single fusion center via their respective direct links and relays. We propose schemes exploiting both quantize-and- forward (QF) and compressive sensing (CS) in relay networks, aiming to take full use of the diversity to recover the original sparse signals through the collection of a small number of samples. Such...
