Abstract:
The present invention is directed to a method for equalizing a radio frequency (RF) waveform in a communication system. The method includes generating a DDS waveform at a predetermined instantaneous frequency. A digital instantaneous frequency signal corresponding to the predetermined instantaneous frequency is provided. A predetermined digital scaling factor corresponding to the predetermined instantaneous frequency is retrieved. The DDS waveform is multiplied by the digital scaling factor to yield an equalized DDS waveform.
