In this paper, a multi-user multi-relay network with wireless energy harvesting (EH) and transferring (ET) is studied. In our system, a simultaneous two-level cooperation, i.e., information-level and energy-level cooperation is conducted for uplink data transmissions (from the users to a destination). Specifically, network coding is employed at the relays to facilitate the information-level cooperation;...
We investigate the downlink performance of relay-aided heterogeneous networks (HetNet). An interference cancellation scheme employed at macro base stations is first proposed based on the cancellation of cross-tier interference from the macro base station to small cell users. Then, we derive the expressions of the probability density function (PDF) and cumulative distribution function (CDF) of the...
Since 3D-TSV technology has been more and more popular aiming at the demand of lightweight and multi-functions of electronic devices in recent years, the μ-C4 bumps with smaller size which interconnect the stacked die will suffer more serious operating stress, and even one of the thousands bumps fails, the device will fail. Hence, it is meaningful to study the reliability of smaller size and higher...

We investigate efficient scheduling algorithms for a relay-aided broadcasting system using random network codes, where our objective is to maximize the transmission efficiency. The broadcast from a base-station (BS) is divided into an information phase and a redundancy phase, where the half-duplex relay assists in the redundancy phase. Time-division transmission is used over packet-erasure channels,...
