Performance analysis of relay-aided millimeter-wave communications with optimal and suboptimal combining at destination

Amplify-and-Forward Relaying With Maximal Ratio Combining Over Fluctuating Two-Ray Channel: Non-Asymptotic and Asymptotic Performance Analysis

“…relaying. Subsequently, several recent works including [2]- [12] focus on the application of relays for mmWave communication, out of which [3], [8], [9], [11] explicitly consider AF relaying.…”

“…for V 1 = V 2 = 0 it reduces to Rayleigh channel model (see [15]-Table I, for details). The FTR model is widely adopted in recent works as an effective mmWave channel model in analyzing different communication schemes, see, e.g., [11], [12], [31]- [38] and references therein.…”

“…In [12] the authors consider DF relaying over the FTR channel. Analytical treatment of DF relaying is fundamentally different from AF relaying.…”

“…For the general case of different σ 2 values, the derived expression for f Z,W (., .) is not as compact, and replacing the result in (12) may not lead to a satisfactory solution.…”

“…Nevertheless, the radio coverage in mmWave band is limited due to its inherent severe penetration loss and scattering effects. Relayaided communications is used to extend the radio coverage in this frequency band, see, e.g., [2]- [12] and references therein. In most of these works however, conventional fading channel models such as Rayleigh, Nakagami-m, and two-wave with diffuse power (TWDP) [13], [14] are considered for characterizing the mmWave channel.…”
