| Abstract | A system and method for the wireless transmission of information signals
between a base station and a plurality of subscriber stations. The method
may include a base station receiving an information signal from trunk
lines for processing for transmission over a RF link to a predetermined
receive unit capable of receiving and processing the information signal,
processing the information signal by assigning pathing for processing the
information signal to be transmitted over a RF link to the predetermined
receive unit, sampling in a predetermined manner the information signal
being processed according to pathing assigned to produce signal samples
representative of the information signal, compressing the signal samples
such that the signal samples may be reconstructed at the predetermined
receive unit to substantially provide the same information as the
information signal provided before being processing, 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 placing the compressed signal samples
representative of the information signal in predetermined, discrete
positions of repeating segments of a transmit signal channel, and
transmitting over a 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. |
