Abstract
A terrestrial Rf telephone system provides a plurality of voice signal channels on a plurality of forward direction carrier frequencies, each carrier frequency having an associated predetermined bandwidth which is designed to accommodate one analog voice signal, and each carrier frequency containing a plurality of slots. The system includes a base station having a plurality of circuit paths for receiving a plurality of forward direction digitized voice signals; a plurality of compressors for compressing the voice signals; a processor for assigning each of the compressed voice signals onto a dynamically assigned frequency/slot; a plurality of channel controllers, each for sequentially combining the compressed digitized voice signals into a single transmit channel bit stream, with each compressed voice signal occupying a respective repetitive sequential time slot in the transmit channel bit stream; and a plurality of modulators for modulating the carrier frequencies. A portion of the carrier frequency within a portion of each slot remains unmodulated by the transmit channel bit stream to provide a phase reference signal.
