الملخص الإنجليزي

Multiple input multiple output (MIMO) techniques are one of the most important technologies in the 4th generation wireless systems, and will have a key role in meeting the requirements of 5G.

Wireless relaying networks (WRNs) have been emerged to avoid the limitations of MIMO by its potential that attains the performance gains of multipleinput multiple-output (MIMO) in networks containing single antenna terminals.

In addition, it can be combined with Space time block codes (STBC), termed as DSTBC, to improve the achieved reliability and spectral efficiency.

Recently, a promising transmission scheme called spatial modulation (SM) has been proposed to provide several advantages over conventional MIMO as: Higher throughput, simpler receiver/transmitter design, and better spectral/ energy efficiency.

Recently, SM has seen further development to yield Quadrature spatial modulation (QSM) which is has a great potential to increase the spectral efficiency and to offer better performance (BER), while preserving the decoding complexity to the same level.

The existing research efforts in either Space-Time-Block-Coded and distributed Quadrature Spatial Modulation are limited.

This thesis proposes a STBCQSM coding technique that is basically dependent on Alamouti‟s STBC code but can be easily extended to other STBC codes.

Unlike QSM, a transmit diversity of 2nd order or higher can be obtained.

Both diversity and complexity of the proposed design is analysed and compared to state-of-art schemes.

Simulation results, which corroborate the theoretical ones, show the effectiveness of STBC-QSM scheme proposed in improving the overall performance and the spectral efficiency.

Moreover a brief explanation for the basis of QSM-STBC in WRNs is introduced.

In addition, this thesis introduces a transmission protocol that adapts QSM into wireless relaying networks, in order to obtain better spectral efficiency and reliability compared to the state-of-art WRN transmission protocols.

In addition, it is analysed theoretically to corporate the included numerically simulation.

It is shown that the performance and gain of the proposed protocol and scheme outperform the state-ofart WRN transmission protocols.
