On ergodic capacity of wireless transmission subject to poisson distributed interferers over rayleigh fading channels
(
IEEE
, 2013 , Conference Paper)
Poisson point process has been widely adopted in the analysis of co-channel interference in dense frequency reuse systems. With the decaying power law, the aggregate co-channel interference in Poisson field can be viewed ...
Optimized Selective OFDMA in multihop network

IEEE
, 2012 , Conference Paper)
Selective OFDMA is a powerfull relaying technique with subcarrier based selection. This scheeme has a high potential to considerably improve the performance of cooperative OFDM systems. However, in practice, the implementation ...
Centralized-decentralized RB allocation based on genetic algorithm and coordination over X2 interface in LTE uplink
(
VDE Verlag GmbH
, 2015 , Conference Paper)
In this paper, we present a method for resource block allocation for the LTE uplink system. It aims to minimize the inter-cell interference and maximize the channel capacity. The genetic algorithm is used to come up with ...
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) ...
Performance of two way opportunistic MAC protocol in non-saturated ad hoc networks
(
IEEE
, 2012 , Conference Paper)
In this paper, performance of relay based MAC protocol for two way traffic is evaluated in non-saturated condition. In real life, non-saturation is more prevalent where nodes are mostly idle. The idea of Two Way ...
