摘要

> >Multiple-receiver digital wireless communication systems employ severalreceivers and a digital central receiver with data fusion to reduce the effectof multipath fading problems. The multiple receiver observations are processedat individual receivers and sent to a digital central receiver. The digitalcentral receiver fuses all the individual receiver data to form global data onwhich symbol was transmitted. In this study, an efficient course resolutionmultiple-receiver approach for reception of slow fading signals in digitalwireless communication systems is proposed. Each individual receiverobservation is represented by course resolution data rather than highresolution data. The proposed approach is investigated for the case of nocoherent frequency-shift keying in slow Rayleigh fading and additive Gaussiannoise. The performance of the proposed approach is evaluated and compared tothat of the optimum low resolution and high resolution approaches. Simulationresults indicate that the proposed course resolution approach is efficient andcost effective. The results also indicate that the proposed approach can beused instead of high resolution approach without noticeable performancedegradation which highly simplifies the construction and design of the digitalwireless communication systems.
