In the article a method of signal processing on the transmitter side is described, utilizing jointly fractionally-spaced equalization and spread-spectrum modulation. Thus two crucial problems of digital signal reliable transmission over the distorting channel with narrowband noise are solved: fractionally-spaced preequalization compensates for intersymbol interference caused by signal dis-tortion, and spread spectrum allows transmission system to be robust against electromagnetic interference. Method efficiency in the sense of error probability and transmit power minimizing is considered.
