Description: (书)现代通信系统使用MATLAB第一章-ALLIANCES is a recently proposed cooperative random access
protocol for wireless networks. In this paper we modify the
original model to include user location information. We also
derive pair-wise error probability (PEP) under Rayleigh flat
fading channel and a power-law attenuation environment.
Based on the PEP analysis we propose an optimal relay
selection scheme, which achieves significant throughput gains as
compared to the random relay selection scheme in the original
ALLIANCES.

Description: Flexible alternating-current transmission systems (FACTS) is a recent technological
development in electrical power systems. It builds on the great many advances achieved in
high-current, high-power semiconductor device technology, digital control and signals
conditioning. From the power systems engineering perspective, the wealth of experience
gained with the commissioning and operation of high-voltage direct-current (HVDC) links
and static VAR compensator (SVC) systems, over many decades, in many parts of the globe,
may have provided the driving force for searching deeper into the use of emerging power
electronic equipment and techniques,
