Improving the Signal-to-Noise Ratio and Coverage of FM Stereophonic Broadcasts
It is a well-known phenomenon that the presently authorized system for FM stereophonic radio broadcasting imposes a significant degradation of the received signal-to-noise ratio when such broadcasts are compared with monophonic transmission. As a consequence, the station coverage area is reduced for both monophonic and stereophonic reception. A new broadcast service, designated FMX, has been developed as a solution to this problem. The improvements that may be achieved are analyzed, and it is demonstrated how audio companding may be implemented in future broadcast transmissions without compromising existing service.
