Pattern Division Multiple Access Featuring Amplify-and-Forward Relaying in an Uplink Network

Amplify-and-Forward Relaying Based Multi-Relay Wireless Network Coding

This paper extends the amplify-and-forward based wireless network coding (AFNC) for single-relay network to multi-relay network with a chain topology. Direct application of the relaying protocol utilized in the conventional single-relay AFNC to the multi-relay scenario causes two major problems: the phenomenon of back stream of data, which we call data reflection, and inter-hop interference. We...

Overview of Amplify- and-Forward Relaying

Cooperative diversity has emerged as a promising technique to combat fading in wireless communications (Sendonaris et. al., 2003a; Sendonaris et. al., 2003b). It is based on the broadcast nature of the wireless medium and enables single-antenna users to “enjoy” space diversity benefits by sharing their physical resources through a virtual transmit and/or receive antenna array. The basic relay c...

An Uplink Proposal Based On Adaptive Interleave-Division Multiple Access

INTRODUCTION systems are expected to achieve the following goals: • Quality of service (QoS) provisioning Packet-based data services (probably using mobile IPv6) Parallel data streams with different QoS classes (supporting hierarchical source coding and video streaming, for example) Low delay • System scalability (w.r.t. data rates, bandwidth, cell sizes, etc.) High peak rates (about 100 Mbps f...

Decorrelate-and-forward relaying scheme for multiuser wireless code division multiple access networks

Decorrelate-and-forward relaying scheme for wireless synchronous code division multiple access (CDMA) networks where multiple sources communicate with a destination supported by multiple relays in flat Rayleigh fading channels is considered. By exploiting equicorrelated spreading sequences, a simple near–far resistant decorrelator together with a beamforming scheme at each relay and the maximal...
