Orthogonal frequency division multiplexing with index modulation (OFDM-IM) has been recently proposed as an efficient technique to improve the error performance and enhance the spectral efficiency achieved by the classical OFDM. In this letter, we minimize the presence of intercarrier and intersymbol interference, experienced by OFDM-IM systems under mobility conditions and multipath scenarios, by...
In this paper, we propose a coordination based resource management (CBRM) scheme with quality-of-service (QoS) provisioning for multicell OFDMA downlink systems. The proposed CBRM scheme cooperates with the multiple point deployment and the enhanced fractional frequency reuse (FFR). To solve the intra-cell interference brought by multiple point deployment, the CBRM scheme adopts a utility function...
When two queues interact with each other, the delay of one queue depends on the behavior of the other queue. More specifically, the delay of one user depends on the access probability of the other user, since this probability controls the level of mutual interference in the network. In this sense, the delay of a given user can be limited by appropriately adjusting the access probability of the other...
