The end-to-end performance of dual-hop wireless communication system with fixed gain relays is investigated over independent non-identical composite Nakagamilognormal fading channels using mixture gamma distribution. Novel closed-form expressions for the outage probability, the average symbol error rate and the nth moments of end-to-end signal to noise ratio (SNR) for the considered system are ...

One of the main drawbacks of cooperative communication systems with halfduplex relaying is inefficient use of spectrum. Incremental relaying is an effective technique that overcomes this limitation, particularly in the high-SNR regime. In this paper, for a multirelay cooperative network with arbitrary number of relay nodes, we propose a spectrallyefficient incremental relaying scheme that elimi...

We present a dual-hop relayed wireless communication system where the gain of the relay, called combined gain relay (CGR), is produced after combining the channel state information from both hops, depending on the mean hop's signal-to-noise ratio (SNR). The proposed scheme can be efficiently applied in dual-hop transmissions with unbalanced mean SNRs due to the long-term fading effects produced...

Based on the increasing property of ratio of average reversed hazard rates of two non-negative random variables a new stochastic order for the sake of comparison of two lifetime distributions is proposed. This stochastic order admits some distinguishing properties. In order to illustrate the obtained results, a semi-parametric model which is called reverse hazard power and a mixture model of pr...

the effects of different levels (0, 10, 20 and 30 percentage of dry matter) of apple pomace ensiled with urea were investigated on 24 ghezel male lambs in a completely randomized design with four treatments and six replicates. the average starting weight and age of the lambs were 31.27 ± 7.40 and 187 ± 37 days, respectively. after 15 days of adaptation, the lambs were individually fed with expe...

the study of the potntial for using leucaena leucocephala or manihot esculentafor supplementing feeding of west african dwarf goats were carried out from november 2003 to january 2004 inthe experimental farm of the universityof dschang. twenty four west african dwarf goats, were divided in three groups of eight animals, each one 12 months old with average weight of 13.1±4.4 kg, were used in thi...
