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. Platform: |

Description: Outage Analysis of Coded Cooperation
Cooperative communication is an emerging paradigm
where multiple mobiles share their resources (bandwidth
and power) to achieve better overall performance. Coded cooperation
is a mechanism where cooperation is combined with—and
operates through—channel coding, as opposed to the repetition-
based methods. Platform: |
