In this paper, we consider an outdoor visible light communication system, in which on–off keying (OOK) modulation is utilized through an atmospheric turbulence-induced slow-fading channel. A new fast blind detection algorithm is proposed by following the generalized likelihood ratio test (GLRT) principle. In addition, a block coding scheme is presented to solve the unique identification issue and,...
Power allocation, relay selection and subchannel pairing are three important issues in OFDM based relay wireless systems to improve the system performance and reliability. In this paper, we will propose a joint power allocation, relay selection and subchannel pairing algorithm. The goal of the algorithm is to maximize the system capacity under the constraint of overall power at both source and relay...
