Besides, in a multiple-antenna system with the help of precoding techniques, it is possible to increase the spectral efficiency by multiplexing multiple users on the same subchannel.
By reducing the so-called safety margins, in the adaptive coding and modulation technique, it is possible to increase the spectral efficiency at expenses of an increased BER on the transmission.
Our work further reveals that, when the effect of mutual coupling is concerned, it is still possible to achieve better spectral efficiency by placing a few more than necessary antenna elements in user equipment and applying an appropriate antenna selection approach than plainly implementing the conventional MIMO system without antenna selection.
Although we will limit our analysis on SC to a preliminary binary case, it would be possible to increase the SC spectral efficiency by extending the presented results to the non-binary case.
Notice that if the relay node suffers too much from self-interference (low attenuation level), the performance of the FD-MH is degraded and it is not possible to achieve the maximum spectral efficiency in the high SNR regime.
To avoid detailed system configurations and to make the performance comparison as general and as consistent as possible, we only use the spectral efficiency as the performance of interest.
This paper proposes a prototype mesh topology network architecture based on regenerative DVB GEO satellites, which enables the interconnection of heterogeneous terrestrial distribution nodes to each other, with minimum possible delay and offering maximum spectral efficiency of the satellite transponder.
In order to improve the spectral efficiency, it is possible to increase either the signal space ΩHR−DSM or the M−PSK constellation.
When full channel state information (CSI) is available at the eNB, it is possible to improve the system's spectral efficiency, albeit proper precoding techniques at the eNB.
Notice that the great advantage of FD relaying is that it is possible to achieve the same maximum spectral efficiency as DT, which is twice the maximum spectral efficiency achieved by HD.
