Abstract
The paper investigates methods to minimise interference between spread -spectrum (SS) radio-location systems and other radio services. Method s to control the power spectral density (PSD) of SS signals are review ed. A novel technique, called 'split-signal', is described which minim ises mutual interference. The technique exploits the noncontinuous use of the radio spectrum by splitting the SS signals into several lower- rate, narrower-bandwidth components. These are transmitted independent ly in gaps in the radio spectrum and recombined at the receiver. It is shown, by analysis and simulation, that the performance of split-sign al SS radio-location systems in comparable to that of conventional wid eband SS systems.
