نویسندگان
چکیده
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 high-pass filtering WCDMA signals is evaluated by UTRA-FDD system simulations.

This paper presents an adaptive multi-target spacetime architecture for downlink receivers in the user terminal of WCDMA systems under soft handoff. The receiver consists of M antennas andK array processors, each one followed by a chip-rate equalizer and a despreader. The resulting signals from these K branches are combined in an adaptive ratio combiner which is updated by the common channel in...
متن کاملAnalysis 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...
