The effect of sinusoidal spurious signals on Mary spreadspectrum communication systems
Abstract
The symbol error probability in the case of narrowband spurious signals can fluctuate for Mary spreadspectrum systems considerably as a function of the interfering frequency. The present investigation has the objective to discuss the functional relations between the symbol error probability and the signal/noise ratio at the receiver input. An approach for the distinct characterization of the transmission quality of Mary spreadspectrum systems in the case of sinusoidal spurious signals is also reported. The conditional error probability for a certain symbol is considered along with the symbol error probability for an arbitrary symbol, and an alternative description of the transmission quality by means of a minimum signal/noise ratio. Under certain conditions, the presented equations make it possible to calculate the symbol error probability directly as a function of signal/noise ratio and of interfering frequency.
