Abstract

In this paper we describe the implementation of a spread spectrum based cooperative relaying on an FPGA platform. We focus on a network comprising one source, one or more relays, and one destination. Once the source's message is received by the relays, the relays simultaneously transmit the information to the destination. In order to avoid interference between the various relay transmissions, each relay node spreads its information using a unique spreading code chosen from a set of sequences with good cross-correlation and autocorrelation properties. These properties allow separation of the signals in the presence of frequency and timing offsets between the various transmissions. This platform is tested through an audio application using a commercially available RF front end. The platform not only enables testing of cooperative communications, but also other related concepts relying on software-defined radio such as Cognitive Radio.

Cooperative communication between cognitive and primary users

The active cooperation between a primary user (PU) and a cognitive user (CU) has the potential of leading to a transmission power reduction and transmission rate increase for both the PU and the CU. Alternatively, the required bandwidth may be reduced and ...
Cooperative spectrum sharing‐based relaying protocols with wireless energy harvesting cognitive user

In this study, the authors consider an energy‐constrained secondary user which harvests energy from the primary signal and forwards this latter with the guarantee of spectrum access. Two key protocols are proposed, namely time‐splitting cooperative ...
