1. A method for processing at least one signal capable of carrying information received from trunk means for transmission over a radio frequency (RF) link to at least one predetermined receive unit, comprising the steps of:

  • (A) receiving the information signal from the trunk means for processing for transmission over the RF link to the predetermined receive unit capable of receiving and processing the information signal;

    (B) processing the information signal received at step (A) by substeps of;

    (1) assigning pathing for processing the information signal to be transmitted over the RF link to the predetermined receive unit,(2) sampling in a predetermined manner the information signal being processed according to pathing assigned at substep (B)(1) to produce signal samples representative of the information signal,(3) compressing the signal samples such that such signal samples may be reconstructed at the predetermined receive unit to substantially provide the same information as the information signal provided before being processed according to step (B), with the compression step resulting in a selective deletion of predetermined portions of the signal samples such that there will be substantially non-degraded, reconstructed signal samples, and(4) placing the compressed signal samples representative of the information signal in predetermined discrete positions of repeating segments of a transmit signal channel; and

    (C) transmitting over the RF link to the predetermined receive unit the portion of each segment of the transmit signal channel containing the compressed signal samples representative of the information signal.
