Abstract
The clipper contained in the standard cellular transceiver used in cellular telephone networks is effectively prevented from having any effect on a signal by reducing the signal amplitude so that the signal which passes through the clipper does not activate the clipper. The signal from the clipper is then re-amplified prior to being passed to the modulator for transmission over the airwaves. The signal power is further increased by adding a selected de-emphasis circuit to the system prior to the transmitter, the de-emphasis circuit causing the frequency components of the signal to decline in amplitude as a function of frequency by a selected amount, 6 dB per octave in one embodiment.
