Energy Detection Based Cooperative Spectrum Sensing in Cognitive Radio Networks (2011, background): “The CSI requirement depends on the AF relaying strategy, in which two types of relays have been introduced in the literature [17], [26]: ∙ Non-coherent power coefficient: the relay has knowledge of the average fading power of the channel between the primary user and itself, i.”
Spectral efficient protocols for half-duplex fading relay channels (2007, background): “2Depending on the amount of channel knowledge at the relay, different choices for the relay gain are possible [14].”
Performance Analysis of the Asymmetric Dual-Hop Relay Transmission With Mixed RF/FSO Links (2011, methodology): “, Rayleigh [1], Rician [2], Nakagami-m [3], Nakagami-q [4], etc.”
Performance Analysis of Mixed Nakagami- $m$ and Gamma–Gamma Dual-Hop FSO Transmission Systems (2015, background): “where 1 denotes the SNR of the RF S–R hop, 2 represents the SNR of the FSO R–D hop, and C stands for a fixed relay gain [12], [16].”
Modulation and demodulation for cooperative diversity in wireless systems (2006, background): “A “blind” relay that does not require instantaneous CSI between the source and relay is proposed in [7], [8]; however, it cannot satisfy an instantaneous power constraint.”
Statistical Analysis of the Multiple Scattering Radio Channel (2006, background): “Here we assume that the analog repeater node (A-F) has fixed gain, which will result in double-Rayleigh signal amplitude (however, noise of the A-F node will affect receiver noise and hence bit error analysis [8]).”
Channel Estimation for Amplify and Forward Relay Based Cooperation Diversity Systems (2007, background): “Relays using gains A1(k) and A2(k) are called fixed gain and variable gain relays, respectively, because A1(k) is constant while A2(k) varies depending on the instantaneous channel [6].”
