Introduction

This specification based JJF 1071-2010 "National Calibration Specifications writing rules" establishment. This specification method for the calibration of the baseband fading simulator, respectively from the reference frequency accuracy of the crystal oscillator path Loss, Doppler shift, the frequency response, the DC bias voltage, spectral purity, path delay, I/Q imbalance, the letter Road path through, aspect function tests were prescribed, and gives a measurement calibration project in the appendix of Uncertainty Evaluation examples. This specification is the first release. Baseband Fading Simulator Calibration Specification

1 Scope

This standard applies to newly manufactured, use the simulator calibration and repair after baseband fading. 2. References This specification references the following documents. JJF 1286-2011 radio channel simulator calibration specification Note. For dated references, only the dated edition applies to this specification; undated reference documents, the most The new version (including any amendments) applies to this specification.

3 Overview

Baseband Fading Simulator input signal sampling, the use of digital signal processing algorithms for digital sampling sequence Treatment and then the digital sequence processed through digital to analog conversion, filtering and other aspects of the output can be fully parametric solid ground Setup signal propagation environment simulation model to simulate Doppler shift, Rayleigh fading, fading signal propagation Special Rice Zheng, with GSM, CDMA, WLAN and other wireless communication standards analog channel capacity, mainly for wireless communication Research and development equipment and product development, manufacturing and evaluation.
