Performance of call admission control techniques for TD-CDMA systems
2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003TD-CDMA (time division code division multiple access) systems adopt a hybrid access scheme. Using different spreading codes several radio carriers are defined on the same bandwidth. On each carrier a time frame is used to multiplex different channels. So a channel is defined by a code and a time slot.

Comparison of the single reflection and total reflection TDS techniques
Journal of Physics E: Scientific Instruments, 1984The single reflection TDS technique is compared with the total reflection technique on the basis of measurements performed on ethanediol and formamide over the frequency range of 108-1010 Hz. While confirming that single reflection TDS does indeed offer superior precision for measurements on high permittivity materials, such as water and formamide, at ...

PARR reduction of TD-SCDMA with Joint Transmission technique
2010 10th International Symposium on Communications and Information Technologies, 2010Joint Detection (JD) technique is used to reduce intersymbol interference (ISI) and multiple access interference (MAI) in current downlink (DL) of Time-Division Synchronous Code-Division-Multiple-Access (TD-SCDMA). However, the technique requires significant calculation and channel estimator in mobile station (MS), causing complexity in MS.

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
An energy-efficient concurrent dual-band Doherty power amplifier (PA) and its related digital predistortion (DPD) for TD-SCDMA and TD-LTE multi-standard wireless communications are investigated in this paper. Due to the proposed inter-modulation tuning technique, the PA efficiency and output power in concurrent operation mode are improved significantly.

Temporal Dominance of Sensations: Construction of the TDS curves and comparison with time–intensity
Food Quality and Preference, 2009 The evaluation of the temporality of the sensory perception in food products is mainly assessed using the time¿intensity (TI) methodology. This approach is useful for studying the temporal aspects of the perception of a given sensory attribute in a ...

A Novel Synchronization Technique Based on Kalman Filter for TD-SCDMA
2010 International Conference on Computational Intelligence and Software Engineering, 2010TD-SCDMA is the 3G mobile communication air interface specification released by International Telecommunication Union (ITU). As a TDD system, synchronization in TD-SCDMA is a key influence factor of Quality of Service (QoS). Considering that mobile communication systems work in the environment of serious interference, multipath propagation and Doppler ...

Advanced FD-TD Techniques for the CAD of 3D Microwave Components
Electromagnetics, 2003Advanced techniques for the finite difference time domain (FD-TD) method are described, which improve the efficiency of the simulation of three-dimensional (3D) microwave components, including structures of more general shape. The formulations are based on a combination of a direct subgrid technique with a locally conformal FD-TD algorithm for ...

Pressure transient analysis for long homogeneous reservoirs using TDS technique
Journal of Petroleum Science and Engineering, 2007Abstract A significant number of well pressure tests are conducted in long, narrow reservoirs with close and open extreme boundaries. It is desirable not only to appropriately identify these types of systems but also to develop an adequate and practical interpretation technique to determine their parameters and size, when possible.
