Evaluation of Impact on Digital Radio Systems by Measuring Amplitude Probability Distribution of Interfering Noise

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 li...

Notched-noise precursors improve detection of low-frequency amplitude modulation.

Amplitude modulation (AM) detection was measured with a short (50 ms), high-frequency carrier as a function of carrier level (Experiment I) and modulation frequency (Experiment II) for conditions with or without a notched-noise precursor. A longer carrier (500 ms) was also included in Experiment I. When the carrier was preceded by silence (no precursor condition) AM detection thresholds worsene...

Noise distribution in the radio frequency spectrum of optoelectronic oscillators.

We analyze the distribution of the rf spectrum in optoelectronic oscillators due to the finite duration of the spectrum measurement. The distribution of the periodogram or the rf spectrum at a given frequency is calculated using a reduced model and is compared to a comprehensive numerical simulation. The model shows that the rf spectrum at a given frequency fluctuates from measurement to measur...

A Method for Converting Amplitude Probability Distribution of Disturbance from One Measurement Frequency to Another

To estimate the impact of electromagnetic disturbances on multi-carrier wireless systems, a method for converting an amplitude probability distribution (APD) of disturbance measured at a frequency to be valid for another frequency is presented. The conversion uses two parameters, the receiver noise power of the APD measuring equipment and a scale factor that can be estimated from a measured dis...

RADIO FREQUENCY NOISE MEASUREMENTS AND MODELS FOR INDOOll

This paper describes . average and impulsive noise measurements inside several office buildings and retail stores. The receiver had a 70-dB dynamic range and operated at 918 MHz, 2.44 GHz, and 4.0 GHz with a nominal 40 MHz 3-dB RF bandwidth. Omni-directional and directional antennas were used to investigate the characteristics and sources of RF noise in indoor channels. Statistical analyseSof -...
