The SRS are physical signals transmitted in uplink to enable the eNB to estimate the CSI over a range of frequencies in LTE system. The estimation of the CSI assists the eNB scheduler to properly allocated radio resource to the UE. The SRS transmission can be also be used to support downlink beamforming. The sub-frame in which SRS is transmitted by any UE within the cell is signaled via cell specific...

Moving cell is one of the new features to further evolve small cell technology for the next generation wireless system. It can be solved the rapid increase of traffic and can be accommodated massive devices. It can enhance the service quality for the users in the moving cell. The deployment of massive device inside the moving cell generates lot of handover calls. The number of group handover scenarios...
Moving cell technology is a concept to further evolve fixed small cell technology for the next generation wireless system which is solved the rapid increase of traffic and can be accommodated massive devices. It provides a continuous connection to the mobile network and moves around its connection network along to the user. A user centric moving cell in LTE-Advanced cellular network is expected to...
A fully integrated tuner IC based on low-IF architecture is developed for triple-band FM/T-DMB/DAB applications. A precise RF gain control with 50 dB dynamic range is achieved in RF VGA by employing a capacitive ladder type attenuator. A novel coarse tuning scheme based on a RF frequency-to-digital converter allows fast and agile automatic VCO frequency calibration, leading to fast locking in PLL...
