Joint channel-aware and buffer-aware scheduling along with rate/power adaptation is a promising solution to assure Quality of Service (QoS) and improve energy efficiency. In this paper, an analytical delay-power tradeoff and optimal threshold-based scheduling are proposed. In particular, we are interested in the scheduling policies where the scheduler only needs to decide transmitting or not. More...
An efficient component-interleaved nonbinary Low Density Parity Check Code (LDPC) scheme is proposed, which can significantly outperform the binary LDPC codes scheme without a component interleaver on fading channels. In this paper, the bit-error-rate (BER) performances of nonbinary LDPC codes are compared with the binary LDPC codes on the independent Rayleigh fading channel. And then we use a fast...
This paper deals with the output feedback quadratic mean square (QMS) stabilization problem for single-input-single-output discrete-time networked control systems. It assumes that the feedback controller interacts with the plant through a communication channel subject to both logarithmic quantization errors and multiplicative random noises. With the knowledge of the quantizer output signal, an observer-based...
Power line communications (PLC) play an important role in smart grid for its cost efficiency. However, the power line is not designed for communication purposes so that its communication environment is hostile with formidable obstacles such as frequency selective fading and impulsive noise. A number of existing methods have been used to deal with the challenges of PLC. Nevertheless, most of existing...
The combination of relay and Multiple-Input Multiple-Output (MIMO) techniques can significantly benefit the signal transmission in cellular networks. In this work, we propose a novel relaying scheme for the relay assisted MIMO broadcast channel including user classification and preceding. The users are firstly classified as Direct Link (DL) users and Relay Link (RL) users according to their channel...
