D2D communication in LTE-A cellular networks can improve overall system performance such as throughput and power consumption substantially and can enable and enhance many proximity based applications. This research topic gains great interest in both academic and industrial fields in recent years. The relevant 3GPP standardization on D2D communication has already begun in several discussion groups...
This paper investigates the one-side interference channel with relay under the exponential power allocation. Usually, the transmitted power linear scaling with the maximum power is used. In this paper, an exponential power allocation is proposed, in which, the transmitted power of each node is presented by an exponential function of the maximum transmitted power with a coefficient. With the exponential...
We develop an optimization technique for a two way asynchronous relay network. A space-time processing based transceiver is proposed for spatial multiplexing in a two-way relay network. The optimization aims to minimize the transmission power at the relays while satisfying the signal to interference-plus-noise ratio (SINR) target for each user. The problem is solved using semidefinite programming.
