In this paper, the end-to-end error performance of conventional dual-hop system where a source communicates with the destination over an energy harvesting (EH) relay in the lack of a direct link between them, is investigated. In the first phase, relay decodes the signal received from the source, from which it harvests energy according to time switching (TS)-based relaying and power splitting (PS)-based...
In this paper, a new cooperative spectrum sharing protocol that employs space-time block coded spatial modulation (STBC-SM) at the secondary user (SU), is proposed for overlay cognitive radio (CR) networks. STBC-SM is applied at the secondary transmitter (ST) which transmits its data by both modulated symbols and antenna combinations while conveying PU's data only by modulated symbols. This protocol...
In this paper, a spectrum sharing protocol that combines coordinate-interleaved orthogonal design (CIOD) and space-time block coding is proposed for cognitive radio (CR) networks. Primary system's transmitter (PT) and receiver (PR) are equipped both by one antenna while secondary system's transmitter (ST) and receiver (SR) are equipped by two and one antennas, respectively. CIOD applied by means of...

An Enterprise Resource Planning (ERP) system is a fully integrated business management system covering functional areas of an enterprise like Logistics, Production, Finance, Accounting and Human Resources. The implementation of this system is a difficult and high cost proposition that places tremendous demands on corporate time and resources. Most of the ERP implementations have been classified as...
In this paper, a new overlay spectrum sharing protocol based on signal space diversity (SSD), is proposed for cognitive radio networks. The considered network comprises of one licensed primary transmitter/receiver (PT/PR) pair and one secondary transmitter/receiver (ST/SR) pair assisting for cooperation before transmitting its own signal on the licensed primary user's spectrum. The overall transmission...
