In particular, the recently proposed technique of distributed spatial modulation (DSM) for relay networks can lead to better spectral efficiency, as it allows the relays to transmit their own data while simultaneously relaying the data of the source. A new distributed spatial modulation protocol is introduced in this paper which achieves virtual full duplex (VFD) communication. In this protocol, the source and relays transmit their own data in every time slot; thus, the spectral efficiency is significantly improved compared to conventional DSM. Simulation results indicate that at high signal-to-noise ratio (SNR), the proposed protocol has similar bit error rate (BER) performance versus SNR-per-bit compared to the standard full duplex relaying protocol of successive relaying; however, in contrast to successive relaying, the relays are simultaneously transmitting their own data, which is received at the destination with an error rate similar to that of the source's data.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Start page:||1||End page:||6||Copyright (published version):||2016 IEEE||Keywords:||Spatial modulation; Virtual full duplex; Relay networks||DOI:||10.1109/PIMRC.2016.7794749||Other versions:||http://pimrc2016.ieee-pimrc.org/||Language:||en||Status of Item:||Peer reviewed||Is part of:||IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC||Conference Details:||The 2016 IEEE 27th Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC 2016), Valencia, Spain, 4-7 September 2016||ISBN:||9781509032549|
