Joint hierarchical modulation and network coding for two way relay networks
(
IEEE
, 2012 , Conference Paper)
The performance of a joint Hierarchical Modulation (HM) and Network Coding (NC) scheme for two way relay networks is introduced and evaluated in this paper. The proposed scheme uses selective relaying based on a signal-to-noise ...
Partial relay selection in underlay cognitive networks with fixed gain relays
(
IEEE
, 2012 , Conference Paper)
In a communication system with multiple cooperative relays, selecting the best relay utilizes the available spectrum more efficiently. However, selective relaying poses a different problem in underlay cognitive networks ...
Area spectral efficiency of cooperative network with opportunistic relaying
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the area spectral efficiency (ASE) in a three-node cooperative network with opportunistic relaying. On one hand, in conventional cellular network, ASE is defined to be the average data rate ...
Area spectral efficiency of cooperative network with DF and AF relaying
(
IEEE
, 2012 , Conference Paper)
Most performance metrics for cooperative networks focus on the qualification of either spectrum efficiency or link reliability, without considering the spatial effect of radio transmission. Area spectral efficiency (ASE) ...
