TLDR
It is shown that the optimal receiver that takes into account demodulation errors at the relays is developed and that it outperforms state- of-the-art cooperative diversity protocols.Abstract:
A cooperative diversity protocol for multi-relay wireless networks is proposed. Its distinguishable feature is to protect the transmission of the source through distributed diversity while simultaneously serving the data traffic of the relays. Therefore, the performance of the source is improved without reducing the aggregate throughput. The protocol exploits a recently introduced concept for multiple- antennas wireless systems, which is known as Spatial Modulation (SM). The contribution of this paper is threefold: i) the optimal receiver that takes into account demodulation errors at the relays is developed; ii) its achievable diversity is studied analytically; and iii) it is shown, with the help of Monte Carlo simulations, that it outperforms state- of-the-art cooperative diversity protocols.read more

Index Modulation Techniques for Next-Generation Wireless Networks
TL;DR: Three forms of IM are investigated: spatial modulation, channel modulation and orthogonal frequency division multiplexing (OFDM) with IM, which consider the transmit antennas of a multiple-input multiple-output system, the radio frequency mirrors mounted at a transmit antenna and the subcarriers of an OFDM system for IM techniques, respectively.

TL;DR: A novel precoding scheme for single-cell downlink MU-SM systems is proposed with a two-fold objective: i) the precoder needs to be able to completely eliminate the Multi-User Interference (MUI) by taking advantage of the Channel State Information at the transmitter and ii) it needs to allow the users to use a single-user Maximum Likelihood (ML) optimum detector while achieving the same performance as interference-free point-to-point SM transmission.

On the Achievable Diversity-Multiplexing Tradeoffs in Half-Duplex Cooperative Channels
TL;DR: Using results one can argue that the suboptimality of previously proposed protocols stems from their use of orthogonal subspaces rather than the half-duplex constraint, allowing for a more efficient use of resources.
