Tsutomu Ishikawa, M. Tanno · IEEE Transactions on Consumer Electronics · 1987
The FMX stereo broadcasting system was developed to extend the servicing area of the stereo broadcasting by CBS. This system is intended to have a great noise reduction affect of approximately 20dB on the stereo noise, maintaining the compatibilities with the normal FM stereo broadcasting. With this system, the stereo broadcasting can cover as large servicing area as the monaural broadcasting.
