Abstract
A method for wireless communication utilizes available channel bandwidth when multiplexing a plurality of user signals over a communication channel. The method utilizes signal power characteristics as a signature to multiplex and de-multiplex the plurality of signals applied to the communication channel. Many wireless communication applications are required to utilize a limited, assigned frequency range. Modulation of digital information in such a limited bandwidth is a critical factor in determining the data transferred through the wireless communication channel. The present invention provides for multiplexing of a plurality of digital data sequences over a wireless communication channel having a fixed frequency range. The method provides for a base station which dynamically assigns signaling power parameters to each remote device which is optimally bandwidth-efficient for present signal traffic loads and for present received power conditions. Depending upon a number of factors, the method improves channel bandwidth utilization by factors of two to three over presently known methods. The communication method may be applied to many communication applications wherein a plurality of …
