چکیده

We show that measurements of time-varying mobile radio channels obtained with uncalibrated correlative channel sounders are affected by four different types of systematic errors (commutation, pulse-compression, aliasing, and misinterpretation error). We analyze these errors and provide upper error bounds that are formulated in terms of channel and sounder parameters. Based on these error bounds, we provide guidelines for a judicious choice of important sounder parameters. Computer simulations using a simple two-path channel illustrate our theoretical results. Finally, we show how our results can be used to assess the accuracy of measured channel data.

Bounds on the Systematic Measurement Errors of Channel Sounders for Time-varying Mobile Radio Channels*

We show that correlative sounders for time-varying mobile radio channels are affected by various systematic measurement errors. We identify and analyze these errors and provide quantitative error bounds in terms of channel and sounder parameters. Furthermore, we propose a novel calibration method yielding substantially improved accuracy. Experiments using measured data and computer simulations ...

Phase Noise Effects on Wideband Mobile Radio Channel Sounding

Abstract – In this work three wideband mobile radio channel sounding methods are simulated and compared using computational tools. The considered sounders include the traditional STDCC and two other proposed sounding methods that are based on OFDM digital transmission and detection procedures and on matched filtering. The impact of the phase noise introduced by the receiver local oscillator in ...

Correlative Channel Estimation in DS - CDMA Systems

The determination of the propagation conditions of time-variant mobile radio channels is a main task in mobile communication systems. For systems based on CDMA, it is generally assumed that the receiver knows the corresponding spreading sequence. Therefore, this sequence can be used for a correlative channel estimation. This paper considers several concepts for the channel estimation in direct-...

The Measurement of Low Frequency Magnetic Field of Two Kinds of GSM900 Mobile Phone

Introduction:  The  use  of  mobile  communication  systems  has  dramatically  increased  over  the  past  decade. Although many studies have been performed to determine the effect of radio frequency (RF) but  less attention has been paid to the possible biological impact of exposure to extremely low frequency  (ELF) components.   The objective of this study is two folds. One is to design the ...
