In this paper, making use of the relaying concept, which enables single-antenna devices to benefit from spatial diversity, a statistical analysis of dual-hop cooperative links using semi-blind (fixed gain) relays and partial relay selection, is provided. The selection scheme considers that the source monitors the connectivity among the nodes (relays) of the first hop only; an interesting assumption...
Scattering problems with multiple canonical scatterers, like cylinders and spheres, may be modeled by utilizing the orders-of-scattering approach. This method provides an exact solution; however, being iterative in nature, the accuracy of the solution depends on the number of iterations; in other words, the number of higher-order scattered fields taken into account. The orders-of-scattering solutions...
Cooperation is emerging as a promising technology to combat the wireless fading and enhance the channel capacity. However,cooperative transmission can not be guaranteed to perform better always than direct transmission, since the statistics of both direct and relay channels are varied due to large scale fading. Therefore, we design an opportunistic criterion to automatically determine which transmission...
