Ultra Broadband Channel Measurement Technology And Measurement Data Post-processing And Parameter Estimation Method Research

This paper is base on the nation project "New General Wideband Wireless Mobile Communication Network"(Project Numbers:2009ZX03006-009)"Technology Specification and Performance Evaluating of UWB Device".On December 6,2008, MIIT [2008]354"about the release ultra-wideband (UWB) technology use frequency regulation of the notice on the use of technology", UWB provisions for 4.24.8 GHz band and 6-9 GHz. Ultra-wideband technology as a formal business may.UWB channel about most of the decline is measuring the statistical characteristics, so about UWB channel measurement method is the main research contents of measurement data post-processing method and parameters estimation method. The data will be used after removing noise, data signal separation technology.The main parameters of UWB transmission channel:Link loss:Broadband power level can be used to describe the whole channel shadows effect.Frequency domain transfer function:In the continuous sub-band average slope and in the correlation coefficient are linked. And because the signal distortion, the frequency response of the research in UWB technology in appear particularly important.Signal delay difference:In the design and optimization of low power equipment, this kind of parameters in the system level design are especially important.This article mainly include the following points:Read a lot of literature material, to understand the characteristics of ultra-wideband technology, application and other technology and are compared.The measurement method, choose channel measurement of frequency domain, to the classroom environment for typical and was measured, acquisition channel characteristic data. Understand the wireless communication channel transmission principle, research of various kinds of transmission model and related parameters, the original data collection for reprocessing and parameter estimation.
