ABSTRACT:
A communication system mitigates signal distortion of output signals transmitted by a transmitter element (406). The communication system obtains parameters related to, inter alia, the number of traffic channels utilized by the system, the number of RF channels utilized by the system, the voltage levels of certain signal waveforms (321) within the system and information related to power levels being transmitted by the transmitter element (406). The communication system utilizes the obtained parameters to, in a first embodiment, clip the signal waveform at certain portions that exceed a determined threshold, and, in a second embodiment, automatic gain control the signal waveform during a symbol time period. By clipping or automatically gain controlling the input signal into the transmitting element (406), the distortion of a signal output from the transmitting element (406) is mitigated.
