Abstract :
The investigation of a spectrum overlay of a direct sequence spread spectrum system on the existing narrowband FM and wideband TV broadcasting system is presented.. Results from subjective listening and viewing tests are presented in order to decide on the RF protection ratios for the FM and TV receivers in an overlay scenarios.
