Heterogeneous Networks (HetNets) are an attractive way of increasing network throughput, expanding network coverage, and reducing energy consumption, but it may lead to the problems of high cost infrastructure investment and high computational complexity to mobile operators. In this paper, we propose a new paradigm for the deployment of HetNets in LTE-Advanced system, where the Donor evolved nodeB...
In TD-LTE-A system, the objective of conventional non-codebook beamforming algorithms is to maximize sum capacity to accommodate more users. However, fairness among users is not considered by these algorithms, and the performance of users with poor channel quality will always be bad. To relax the fairness requirement in resource allocation, this paper first introduces two parameters of user satisfaction...
Joint transmission (JT) is a promising coordinated multipoint (CoMP) transmission scheme for achieving high downlink capacities in wireless cellular networks of next generation. In this paper, an adaptive scheme, named as partial JT CoMP is presented. This scheme improves the network throughput by dynamically adjusting points involving in jointly transmitting according to the instantaneous channel...
The TDRSS is a network of communication satellite and ground stations used by NASA for space communications. In the article, we do an accurate link analysis based on TDRSS and simulate the communication between the two satellites by using OPNET, the use of actual and real data and the final BER result show that such a communication link is feasible using small LEO satellite which is a part of a satellite...
