“…Atapattu [12] analysed energy detection performance for a fixed gain relay network over only Rayleigh channels using complementary AUC analysis, but the derivation is not in generalized form and the solution is intricate. In [13] and [14], detail performance studies of dual-hop end-to-end transmission system with fixed relay gain are found but not the energy detector's performance. The existing solutions mainly deal with the perfect i.i.d.…”

Relay based cooperative spectrum sensing elevates the spectrum sensing problems in harsh propagation conditions if the relay nodes are positioned suitably for the dynamic spectrum access systems. This article investigates the performance of relay based spectrum sensing (energy detection based) in myriad fading environments using the area under the receiver operating characteristic curve (AUC) performance metric. AUC is a single statistical parameter, which provides better insight of detection probability compared to the receiver operating characteristic curve (ROC). The article includes the performance analysis of two-hop multi-relay amplify-and-forward (AF) relay network with channel state information (CSI) assisted relaying (variable relay gain) and blind (fixed) relay gain. A unified model is also

“…The end-to-end SNR of AF dual-hop relaying systems, denoted by γ c , has a well-known form [10], [9], which generally can be expressed as γ c = γ1γ2 γ1+γ2+b , where γ 1 and γ 2 are the combined SNRs on the first and second hops respectively, and b is a constant. The case when b = 0 represents the channel-assisted relay configuration, whereas b = 1 gives the channel noiseassisted relay configuration.…”

Abstract-This paper investigates the effect of different switched diversity configurations on the implementation complexity and achieved performance of dual-hop amplify-and-forward (AF) relaying networks. A low-complexity model of the relay station is adopted, wherein single-input single-output antenna configuration is employed. Each of the transmitter and the receiver however employs multiple antennas to improve the overall link performance. Single-phase and two-phase based receive switching strategies are investigated assuming optimum first hop signal-to-noise ratio (SNR). Moreover, the simple scheme in which the switched diversity is applied independently over the two hops is studied using tight upper bounds. Thorough performance comparisons and switching thresholds optimization for the aforementioned strategies are presented. Simulation results are also provided to validate the mathematical development and to verify the numerical computations.
