A real zero SSB transceiver for land mobile radio: A simple method of demodulating SSB signals without an envelope

A real zero single sideband (RZ SSB) transceiver is newly proposed for mobile radio services. The necessary transmission bandwidth of RZ SSB is similar to that of a conventional SSB. In this new transceiver, an amplitude limiter, which can remove the amplitude impairment, can be used without degrading the quality of detected output signals in the receiver. Furthermore, since RZ SSB signals possess FM-like characteristics, they can be demodulated with frequency detection as well as product detection.
