Abstract :
The contribution is primarily concerned with the transmission of speech over a 942 MHz tone-above-band SSB mobile radio link. It has been found that the use of feedforward signal regeneration enables a speech quality to be obtained in the Rayleigh fading environment which is superior to that achieved by a conventional 25 kHz FM system. Finally, a new optimised form of SSB, phaselocked transparent tone-in-band, is shown to be also capable of transmitting and receiving coherent data such as CPSK in the mobile radio environment.
