Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
( IEEE , 2011 , Conference Paper)Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ... -
Performance analysis of selective cooperation with fixed gain relays in Nakagami-m channels
( elsevier B.V. , 2012 , Article)Selecting the best relay using the maximum signal to noise ratio (SNR) among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay ... -
Performance of relay-assisted soft handover
( IEEE , 2009 , Conference Paper)This paper examines the effect of relay-assisted soft handover on the performance of the uplink communication in the third generation mobile networks. We focus on users which are traveling over two cell boundaries in a ... -
Power loading algorithms for SEC diversity schemes
( IEEE , 2007 , Conference Paper)Switch and Examine Combing (SEC) diversity scheme is one of the simplest diversity schemes to combat fading. When the power used for probing the channels in this scheme is fixed, it can be higher than what is actually ... -
Reactive relay selection in underlay cognitive networks with fixed gain relays
( IEEE , 2012 , Conference Paper)Best relay selection is a bandwidth efficient technique for multiple relay environments without compromising the system performance. The problem of relay selection is more challenging in underlay cognitive networks due to ... -
User cooperation schemes in the soft handover regions
( IEEE , 2009 , Conference Paper)This paper examines the effect of relay-assisted soft handover on the performance of the uplink communication in the third generation mobile networks. We focus on users which are traveling over two cell boundaries in a ...
