Joint Subcarrier Pairing and Power Allocation for OFDM Transmission With Decode-and-Forward Relaying
TLDR
In this paper, a point-to-point orthogonal-frequency- division multiplexing (OFDM) system with a decode-and- forward (DF) relay is considered. Expand

Adaptive closed-loop power control with quantized feedback and loop filtering
TLDR
We propose a new power control scheme which has several novel features: it uses an adaptive optimal quantizer at the receiver for transmitting discrete feedback information and an adaptive quantization scaler/restorer followed by a loop filter at the transmitter. Expand

On Secrecy Rate of the Generalized Artificial-Noise Assisted Secure Beamforming for Wiretap Channels
TLDR
We propose a generalized artificial noise assisted beamforming scheme which allows the injection of the artificial noise to the legitimate channel to disrupt the eavesdropper's reception. Expand

Space-time turbo codes with full antenna diversity
TLDR
In attempting to find a spectrally and power efficient channel code which is able to exploit maximum diversity from a wireless channel whenever available, we investigate the possibility of constructing a full antenna diversity space-time turbo code. Expand
