Double-Rayleigh fading channelsIn this paper, we investigate physical-layer security performance of the cooperative vehicular relaying networks, wherein the communication from a source vehicle to the destination vehicle is assisted by an amplify-and-forward (AF) relay vehicle in the presence of a ...
case A (the first hop is the Rayleigh fading channel and the second hop is double Rayleigh fading channel) and case B (two hops are the double Rayleigh fading channels). From these obtained mathematical expressions, the impacts of the distances between the communication nodes and the residual ...
Performance of downlink NOMA-enabled vehicular communications over double Rayleigh fading channels Non-orthogonal multiple access (NOMA) is an attractive candidate for future wireless networks. Recently, vehicular communications with NOMA have received s... N Jaiswal,N Purohit - 《Iet Communications》 被...

Comparison of the level crossing rate and average fade duration of\nRayleigh, Rice and Nakagami fading models with mobile channel data Level crossing rate (LCR) and average fade duration (AFD) of the signal envelope are two important second-order channel statistics, which convey useful inf... ...
,N) denotes Rayleigh fading coefficients when signal is transmitted from Si to Rk. We assume the channel is quasi-static during one frame, and is changed independently when one frame is over. Channel noise nkR is assumed to have a distribution CN(0,N0∕2). In the second phase, Rk ...
The double Rayleigh fading channel is of particular interest to vehicle-to-vehicle communication systems as well as amplify-and-forward relaying and keyhole channels. This paper studies the performance of HARQ-CC over double Rayleigh channels from an information theoretic perspective. Analytical ...
Numerical results show the impacts of the double Rayleigh fading channels on the system performance in comparison with those of Rayleigh fading channels. Moreover, the effects of the distance, path loss exponent, and residual self-interference (RSI) on the system performance are also studied. We ...
