چکیده

Assuming the use of GSM/UMTS co-sitting for initial 3G network deployment, real data extracted from the GSM network can be used to optimise 3G planning and RRM issues. It has been developed a 3G planning simulation tool which instead of using theoretical models, benefits from the availability of realistic propagation, mobility, as well as spatial and temporal traffic distributions. The tool is used in this paper to study the effects of Pilot Power and Active Set parameters in both, uplink and downlink capacity, in a real urban scenario, thus anticipating the expected behaviour of UTRA-FDD in such conditions.

Admission and cell congestion analysis through dynamic power allocation

This paper studies the influence of the Active Set main parameters in different UTRA-FDD scenarios by evaluating the system capacity, as well as BS and UE transmitted power levels. Some of the parameters obtained as outputs of the proposed Power Control algorithm (PC) can be also easily used to optimise the admission procedure and scenario capacity, while avoiding cell congestion.

Down-link beamforming effects on the code orthogonality in UTRA-FDD systems

A novel approach in quantifying code orthogonality factor for UTRA-FDD systems is extended in this paper to include the impact of down-link beamforming. The effects of fixed beam forming on code orthogonality is analysed through the aid of real channel data taken from urban cellular environments. The results show a significant overall improvement in code orthogonality with beam forming, especia...

CPICH power optimisation by means of simulated annealing in an UTRA-FDD environment - Electronics Letters

Introduction: Because of the use of rake receivers and the introduction of a soft handover scheme in UTRA-FDD, there are areas of operation in which user equipments (UE) are connected to a group of base stations (BS) known as the ‘active set’ (AS). Since the network orders the UE to add a BS to its AS according to quality measurements made on the primary scrambling code of the common pilot chan...

Feasibility Study of DC Offset Filtering for UTRA-FDD/WCDMA Direct-Conversion Receiver

This paper presents a feasibility study of DC offset filtering for direct-conversion UTRA-FDD/WCDMA receivers. Spectral characteristics and properties of continuous transmission facilitate the use of simple high-pass filtering and this method is evaluated in the paper. Design equations for DC offset power to down-converted signal power ratio are presented and the impact on bit error rate of hig...

Analysis of closed loop power control modes in UTRA-FDD under time varying multipath channels

Fast power control is perhaps the most important aspect in a WCDMA system like UTRA-FDD. In this paper, closed loop power control procedures in UTRA-FDD are studied. A physical layer simulator, which has been implemented in the C language from the standard of the UTRA-FDD mode [1]-[4], has been the tool to get the results included in this research. Simulations have been made for different mobil...
