Performance of SIR-based power control for UMTS
The performance of SIR-based closed-loop power control (CLPC) for the W-CDMA UTRA-FDD uplink has been evaluated. The evaluation work has been carried out using the standard deviation of the power control error (PCE) as the performance metri...
Performance evaluation of power control algorithms in cellular UTRA systems
The CDMA based UMTS transmission technology in which all users simultaneously share the same common range of spectrum gets rather affected by the system interference. The reduction of interference is therefore a key issue in the development...
Performance of power-triggered and Ec/N0-triggered soft handover algorithms for UTRA
A dynamic adding and dropping thresholds based soft handover algorithm proposed for the UTRA system is evaluated through simulations. The simulations are carried out in an UMTS vehicular environment. Two possible handover triggering schemes...
System performance of multi-sector smart antenna base stations for WCDMA
In this paper, a novel approach is proposed for system level simulation of both beamforming and diversity antennas for WCDMA base stations. In order to obtain more accurate system level performance, the proposed approach takes into account ...

The effects of inter-system interference in UMTS at 1920 MHz
The Universal Mobile Telecommunications System (UMTS) is composed of an FDD and TDD mode. Both modes have an adjacent carrier at 1920 MHz. The implications thereof for system capacity are analysed. In this context, the FDD mode is assumed t...
Linear multi-user detectors for TDD mode of UMTS (IMT-TC)
We have examined the effect of multi-user detectors for the TDD mode of wideband CDMA, particularly the downlink. It is shown that under dispersive conditions a RAKE receiver suffers from a high mean square error at its output when all the ...
Multiple code adaptive despreader for UTRA TDD
A modified version of the minimum mean square error receiver to be used with UTRA TDD mode is presented in this paper. The structure is tested in a multipath fading channel and its equalisation and multipath access interference suppression ...
Technology requirements of the 3GPP-TDD terminal
This paper examines the technology requirements for the implementation of the 3GPP-TDD mode and discusses how the terminal complexity of the TDD mode compares to that of the FDD mode. An overview of the TDD mode covers the frequency bands, ...
