Abstract
Direct-sequence spread-spectrum transmissions are increasingly employe d in terrestrial radio-location systems to minimise interference with narrowband communications services in shared bands. Further flexibilit y in band planning is afforded by a scheme proposed recently to genera te from the high-rate sequence an integral number of lower-rate, narro w-bandwidth, 'split-signal' sequences which are transmitted in availab le gaps in the spectrum. The paper shows that the bandwidth and power density of the transmission may be further controlled by overlapping o r interleaving the spectra of the split signals without unacceptable d egradation of positioning performance due to their mutual interference .
