Cooperative communications scheme with interference management under ICI for OFDM LTE-A systems
(
IEEE Computer Society
, 2013 , Conference Paper)
In long term evolution (LTE) systems, the achievable cell spectral efficiency is often limited by the inter carrier interference (ICI) or coverage shortage of base stations. Hence, in LTE-Advanced, cooperative communication ...
Performance analysis of relay selection schemes in OFDM-based underlay cognitive networks
(
IEEE
, 2013 , Conference Paper)
Cognitive radio (CR) is a promising technology that allows wireless systems to sense the environment and learn from previous experience to improve the communication quality. However, CR needs a flexible and adaptive physical ...
