METHOD AND APPARATUS FOR PEAK-TO-AVERAGE RATIO CONTROL IN AN AMPLITUDE MODULATION PAGING TRANSMITTER

摘要

A method and apparatus for reducing peak-to-average power ratio in a paging transmitter broadcasting and independent sideband amplitude modulation protocol is disclosed. A digital signal (xl(n), xu(n)), for example a digital voice signal, is provided to a control gain generator (103) which generates a digital gain sequence. The digital gain sequence is such that during peak values in the digital signal the gain is low and during low values in the digital signal the gain is high. The digital gain sequence is multiplied (104) with the digital signal to compress the dynamic range of the digital signal.
