Improved sphere decoding algorithm in TD-LTE system
2011 IEEE 3rd International Conference on Communication Software and Networks, 2011In the MIMO-OFDM detection algorithm, the performance of sphere decoding most approach that of the Maximum Likelihood algorithm. However, the complexity of traditional sphere decoding algorithm is still relatively high. To solve the above difficult problems, some improvements are made based on the detail analysis of the principle of the sphere decoding

D2D Mobile Relay in TD-LTE-Advanced System
Applied Mechanics and Materials, 2015The UEs at the edge of the cell in TD-LTE-Advanced system suffer from a poor communication quality invariably. In this paper, a novel relay mechanism, called Device-to-Device mobile relay (D2DMR), is proposed. In the D2DMR mechanism, the UE at the edge of the cell or in a poor coverage area can communicate with eNodeB via another UE’s relay.

Understanding ENodeBs traffic dynamics in TD-LTE network
2017 IEEE/CIC International Conference on Communications in China (ICCC), 2017With lower latency and higher bandwidth than its predecessor 3G networks, the latest generation LTE has been more attractive. Benefiting from the big data in LTE network, it is possible to make the analyses one step further into the Evolved Node B (eNBs) level.

Coordinated multi-cell beamforming for TD-LTE-advanced systems
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011LTE-Advanced systems are built upon the orthogonal frequency division multiple access (OFDMA) technology, which can effectively eliminate the intra-cell interferences, but cannot automatically mitigate the inter-cell interferences (ICI). Coordinated multi-point transmission/reception (CoMP) is one of the candidate enhancement techniques for LTE ...
