“…In some cases, the contribution of the terms with k > 1 in Eq. (29) can be ignored because the subchannel bandwidth of a multicarrier system is usually much narrower than the total bandwidth, which reduces the impulsiveness of the input noise [37], [38], [46].…”

“…The APD was used for characterizing an electromagnetic environment to estimate the communication performance of newly introduced radio systems [26]- [33]. APD-based analyses were conducted to evaluate co-channel and adjacent channel intersystem interference [14], [34]- [36] and to predict the impact of noise from household appliances on digital TV reception [37], [38]. The usefulness of APD measurement was also demonstrated for resolving intra-system interference issues, e.g., evaluating the self jamming effect on communication performance and mapping the noise intensity on a printed circuit board [39]- [43].…”

SUMMARY This paper presents a method for evaluating the maximum bit error probability (BEP) of a digital communication system subjected to interference by measuring the amplitude probability distribution (APD) of the interfering noise. Necessary conditions for the BEP evaluation are clarified both for the APD measuring receiver and the communication receiver considered. A method of defining emission limits is presented in terms of APD so that the worst BEP of a communication system does not exceed a required permissible value. The methods provide a theoretical basis for a wide variety of applications such as emission requirements in compliance testing, dynamic spectrum allocations, characterization of an electromagnetic environment for introducing new radio systems, and evaluation of intra-system interference. key words: amplitude probability distribution, electromagnetic interference, electromagnetic noise, bit error probability, non-Gaussian noise

“…Transient interferences have short time durations; however, they can produce strong degradation to digital communication systems, and especially to realtime communication systems as retransmissions are not allowed due to their real-time nature. A typical example is the degradation produced by this impulsive type of interference to the digital video broadcasting terrestrial (DVB-T) [4], [5]. Another example of a digital communication system interfered by radiated transient noise is the GSM-Railway system.…”

Radiated transient interferences produce severe errors to digital communication systems. Conventional measurements defined in the electromagnetic compatibility (EMC) standards are not sufficient to predict the impact of this impulsive noise on the quality of a digital system, as measurements were originally defined to protect analogue communication systems. Measurement detectors and methods based on reaching the statistical of the interference have been studied as the best option to evaluate transient interferences. For a properly EMC emissions evaluation, an amplitude probability detector (APD) has been recommended as the best option, since APD results have been correlated with bit error probability. However, carrying out APD measurements using electromagnetic interference (EMI) receivers has strong inconvenience. One of the main limitations is that measurement can only be performed with the preset filters available at the EMI receiver, which sometimes are different from the communication bandwidths causing an incorrect estimation on the degradation produced. Another restriction is the elapsed time needed to acquire the statistical APD measurement at each frequency band. This document presents a methodology to obtain the APD measurement at any frequency band employing two single time-domain oscilloscope captures. The developed measurement method makes it possible to obtain the APD at any frequency band achieving as good results as the ones acquired from EMI receivers. To show the effectiveness of the time-domain method, an exhaustive validation study is presented, in which white Gaussian noise and several impulsive interferences are evaluated at frequencies from 50 MHz up to 1 GHz.

“…In fact, it is known that fluorescent lamps using highfrequency electronic ballasts generate significant noise electromagnetic fields [7,8]. Most recently, the noise generated by the power circuits of light-emitting diode (LED) lamps has been actively discussed [9]. If the transceiver is in the vicinity of such noise sources and is immersed in the noise electric fields, the noise should directly be transmitted to the transceiver even if the transceiver is not connected to the grounding system.…”

In the development of intrabody communication systems, the most challenging goal is to protect against noise due to other electronic devices. In this regard, it is known that fluorescent lamps using highfrequency electronic ballasts generate significant noise in electromagnetic fields. In this paper, we conduct an experiment of noise voltage received by a wearable transceiver in the presence of fluorescent lamps using high-frequency electronic ballasts, and show that the noise electric fields generated by the lamps result in a significant level of the received noise voltage.
