Recently, amorphous cells emerge as a promising paradigm in cellular networks to support bursty traffic caused by the user mobility, where dense small cells can cooperate on data delivery to mobile users thus implementing coverage without definite cell shape. In this paper, we propose a novel small cell deployment scheme, aiming at optimizing the network(More)
In this paper, we develop an iterative receiver with interference suppression for long term evolution (LTE) downlink systems. The key challenge here is how to accurately estimate the channel state information and spatial covariance matrix of interference by using limited available pilots in LTE systems to improve the interference capability and the(More)
To deal with problems that queuing information is not included in cognitive information when performing Resource Allocation (RA), a dynamic cross-layer scheme is proposed for the multimedia cognitive radio (CR) system with Orthogonal Frequency Division Multiplexing (OFDM). In this scheme, we consider that several crucial factors influence the RA decision,(More)
Recently, Ultra Dense Network (UDN) emerges as one of the state-of-the-art technologies to cope with the pressure of the ever-growing traffic demands in wireless communication. By deploying dense Base Stations (BSs) to provide ubiquitous coverage and high-speed transmission, it is considered as one of the most promising paradigms. However, large numbers of(More)
