Outage probability of a cooperative maximum ratio transmission

open access: yes2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
In this paper, we present a cooperative communication system employing maximum ratio transmission technique and its outage probability performance over Rayleigh fading channels. Since maximum ratio transmission can achieve full diversity when used at tranmitters having multiple antennas while requiring no complexity increase at the receiver, the ...

Exploiting Tradeoff Between Transmission Diversity and Content Diversity in Multi-Cell Edge Caching

open access: yes, 2018
Caching in multi-cell networks faces a well-known dilemma, i.e., to cache same contents among multiple edge nodes (ENs) to enable transmission cooperation/diversity for higher transmission efficiency, or to cache different contents to enable content ...
