“…We will consider the pulse amplitudes to follow a lognormal distribution [10]- [12]. According to the property which states that the logarithm of a log-normal variable is a normal variable, we will express the MMN power in dBμV, and therefore in order to generate the amplitude we will generate a normal variable X of mean=A dBμV and standard deviation=B dB.…”

Man-made noise (MMN) appears as samples of high amplitude when demodulated by a digital receiver. When the effect of MMN pulses over a specific communication system is researched it is useful to know what can be expected about the pulses in terms of amplitude, phase, duration and time between two consecutive ones. In this paper we describe what parameters are needed in order to appropriately characterize MMN in a practical way, and how we can use these parameters to generate MMN sequences that would be added to the demodulated original signal if we want to research the impairing consequences. As a practical application, this paper also presents the development of a digital MMN generator for testing communication system impairment.

This paper describes a technique to measure noise emissions from electrical appliances and study their impact towards digital communication systems by using the amplitude probability distribution (APD) methodology. The APD has been proposed within CISPR for measurement of electromagnetic noise emission. We present a measurement approach which utilizes a programmable digitizer with an analysis software to evaluate the noise APD pattern and probability density function (PDF). A unique noise APD pattern is obtained from each measurement of noise emission from different appliances. The noise PDF is useful for noise modeling and simulation, from which we can estimate the degradation on digital communication performance in terms of bit error probability (BEP). This technique provides a simple platform to examine the effect of other electrical appliances noise emission towards specific digital communication services.

“…Nowadays, an important cause of electromagnetic incompatibilities and interferences are broadband impulsive noise disturbances unintentionally produced, i.e., by sparks or switching power supplies that propagate as radiated signals affecting digital communication systems receivers as in-band interferences [1]. This is the case of several contemporary applications such as Digital Video Broadcasting Terrestrial (DVB-T), Trans European Trunked RAdio (TETRA), Radio Frequency IDentification (RFID) and GSM-Railway system that are susceptible of degradation in their performance under the impact of transient broadband interfering noise [2] [3].…”

“…Those CISPR compliant FFTbased EMI receivers tend to reduce the measurement time spent in the conducted and radiated emissions test by several orders of magnitude [1] [5]. Nevertheless, in general terms, those TDEMI systems have been more focused on emulating the functioning, specifications and performance of the stateof-the-art EMI receivers that operate in the frequency domain than in performing a more comprehensive evaluation of the electromagnetic disturbance in the time domain [6].…”

Abstract-This paper presents a measurement system intended to be used to assets the radiated electromagnetic interference (EMI) in both time and frequency domains. In order to keep the measurement setup as accessible and practical as possible, the direct measurements are recorded with a general purpose digital oscilloscope and processed with a commonly available personal computer. The measurement system was validated for radiated emissions testing using well-known, controlled transient and continuous signals emulating typical interferences. The results are in satisfactory agreement with those provided by a conventional EMI receiver for different types of detectors. The proposed approach shows that, currently, it is possible to implement a timesaving, accurate and generally inexpensive time domain measurement system for radiated emissions that is capable to overcome the limitations of the superheterodyne EMI receivers regarding the measurement of discontinuous electromagnetic disturbances and also able to provide additional enhanced features to evaluate and troubleshoot EMI problems.
