Cooperative communication has been considered as a promising method for benefiting the advantages from MIMO (multiple-input multiple-output) system for single antenna mobiles in the wireless network, and many important milestones in this area have been achieved, leading to a flurry of research activity. Especially, cooperative communication in wireless sensor networks (WSNs) has gained so much interest...
This paper, proposes a Radio Network Planning for Fixed WiMax Network for Dhaka City. To develop the plan a cell radius of 400 meter is assumed. For the justification of this assumption several numbers of experimental analyses are done. Two experiments are executed to know the data speed with respect to the distance both for uplink and downlink communication. Another two experiments are executed for...
In this paper, a Gaussian multiple input multiple output multiple eavesdropper (MIMOME) channel is considered where a transmitter communicates to a receiver in the presence of an eavesdropper. We present a technique for determining the secrecy capacity of the multiple input multiple output (MIMO) channel under Gaussian noise. We transform the degraded MIMOME channel into multiple single input multiple...
