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)
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)
In this paper, we investigate the inter-cell interference mitigation through mode selection of coordinated multi-point (CoMP) techniques in downlink LTE-A networks. The proposed scheme selects the single-cell (SC) or coordinated beamforming (CB) or joint processing (JT) transmission mode according to interference level to maximize the sum rate. We propose a(More)
