In cognitive radio networks, a secondary user (SU) equipped with radio frequency (RF) energy-harvesting circuits can not only harvest the RF energy from the primary transmitter, but also recycle its self-power when transmitting. In this paper, we are concerned with the following design metrics: SU's harvested energy, SU's energy efficiency, and SU's harvesting efficiency, which is defined as the ratio...
Spectrum efficiency (SE) and energy efficiency (EE) are two key targets in wireless communication networks. Applying energy harvesting technology to cognitive radio networks (CRNs), which is called RF-powered CRNs, provides an effective method to improve both SE and EE of CRNs. In conventional RF-powered CRNs, secondary transmitters (STs) equipped with RF energy harvesting capability opportunistically...
Network coding (NC) is a promising method used to achieve the channel capacity and enhance the reliability of multicast networks. However, the general wireless multicast networks based on NC are facing big problems such as long delays and large computational complexities. We propose a multicast network based on Batched sparse (BATS) codes which can efficiently solve these problems. Since fountain...
We consider central traffic engineering in a software-defined radio access network (SD-RAN) consisting of routers, wireless access nodes, and wired/wireless links. We present a multi-path traffic engineering formulation for downlink transmission considering both backhaul and wireless access constraints. We show large throughput and quality of experience (QoE) gains over traditional single-path transmission...
This paper presents a VLSI architecture of CABAC decoder for H.264/AVC level 5.1 applications. It adopts a symbol-prediction-based decision engine with extra-bypass decoding support, a four-stage bypass engine, along with dedicated arithmetic decoding modes to increase the throughput rate. It also reduces the context model access time significantly by applying context pre-fetch register set. The proposed...
In this paper, we present a high-throughput deblocking filter architecture for H.264/AVC in QFHD applications. In order to enhance the parallelism of filtering without notably increasing the area, we propose to parallelize the processing of luminance and chrominance samples, instead of simultaneously filtering two edges of a same component. Although the edge filter and transpose cost of the proposed...
