Analysis of spurious spectrum due to RF bursting signals in TDMA-based wireless communications systems

摘要

This paper is to analyze the characteristics of the spurious spectrum due to the RF bursting signals and its potential interaction with surrounding electronic equipment. The spurious spectra at different mode of transmissions in TDMA-based systems are discussed using FFT. The mechanism of the interaction is described on the base of the spectrum analysis. It is proved that that the level and feature of the interference would be basically determined by four factors: transmitter output power, RF carrier frequency, duty cycle, rise/fall time, repetition frequency of the RF pulses, modes of RF transmission, as well as the immunity of receptive equipment.
