TD-LTE Coverage Planning Targets and UL/DL Subframe Configuration

open access: yesDianxin kexue, 2013
Common reference signal received power(CRS RSRP)and signal interference noise ratio(CRS SINR)are two important wireless network planning factors,which are directly related to indoor deep coverage and edge data rate.

Maximum SINR Synchronization Strategies in Multiuser Filter Bank Schemes

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
We consider synchronization in a multiuser filter bank uplink system with single-user detection. Perfect user synchronization is not the optimal choice as the intuition would suggest.

Random Matrix Theory Predictions of Dominant Mode Rejection SINR Loss due to Signal in the Training Data

open access: yesIEEE Open Journal of Signal Processing
Detection and estimation performance depends on signal-to-interference-plus-noise ratio (SINR) at the output of an array. The Capon beamformer (BF) designed with ensemble statistics achieves the optimum SINR in stationary environments.

The effect of phosphate deficiency on quorum sensing signaling pathway of Sinorhizobium meliloti

open access: yesBiological Journal of Microorganism, 2015
Introduction : Phosphorus is one of the most essential macroelements for bacterial cells. Since phosphate (PO4-3) limitation is frequently encountered in soils, bacteria developed some mechanisms in response to this sever condition. Phosphate transporter

Supervised AutoEncoder-Based Beamforming Approach for Satellite mmWave Communication

open access: yesInternational Journal of Antennas and Propagation
Beamforming is a technique commonly used in wireless communication systems to enhance the signal quality of a receiver. In this study, we compare the performance of an encoder-based beamformer with convolutional neural network (CNN) and minimum variance ...
