Performance Comparison of Relay-Based Covert Communications: DF, CF and AF
Sensors, 2023 In this paper, we investigate the performance of covert communications in different types of a relay system: decode-and-forward (DF), compress-and-forward (CF) and amplify-and-forward (AF).

mmWave Amplify-and-Forward MIMO Relay Networks With Hybrid Precoding/Combining Design [PDF]
IEEE Transactions on Wireless Communications, 2019 In this paper, we consider the amplify-and-forward relay networks in mmWave systems and propose a hybrid precoder/combiner design approach. The phase-only RF precoding/combining matrices are first designed to support multi-stream transmission, where we ...

Approaching Gaussian Relay Network Capacity in the High SNR Regime: End-to-End Lattice Codes [PDF]
, 2013 We present a natural and low-complexity technique for achieving the capacity of the Gaussian relay network in the high SNR regime. Specifically, we propose the use of end-to-end structured lattice codes with the amplify-and-forward strategy, where the ...

Cooperative Spectrum Sensing Schemes with the Interference Constraint in Cognitive Radio Networks
Sensors, 2014 In this paper, we propose cooperative spectrum sensing schemes, called decode-and-forward cooperative spectrum sensing (DF-CSS) scheme and amplify-and-forward cooperative spectrum sensing (AF-CSS) scheme, in cognitive radio networks.

Differential Amplify-and-Forward Relaying in Time-Varying Rayleigh Fading Channels [PDF]
, 2013 This paper considers the performance of differential amplify-and-forward (D-AF) relaying over time-varying Rayleigh fading channels. Using the auto-regressive time-series model to characterize the time-varying nature of the wireless channels, new weights
