Setting a transmission power level for a mobile unit
View Patent ↗A spread signal is produced having an adjustable spread spectrum. A data signal is provided for transmission. The data signal is processed to have a first spread spectrum. The processed first spread spectrum data signal is filtered to have one out of a plurality of spread spectrums. The filtering capable of producing a signal having a spread spectrum of any of the plurality of spread spectrums. The filtered one spread spectrum data signal is transmitted.
