20080299919 | SIGNAL ENHANCEMENT IN RF TRANSMITTERS EMPLOYING NON-LINEAR FILTERING - A communications transmitter having a main transmit chain for main signal features and one or more auxiliary transmit chains for auxiliary signal enhancements. In one embodiment, a communications signal is produced by digitally processing a representation of a desired signal so as to limit a trajectory of a signal represented by a resulting processed signal. A digital representation of a difference signal approximating a difference between the processed signal and the desired signal is produced.

The first modulated, amplified signal and the second modulated, amplified signal are combined to produce the desired signal. In this manner, a main transmit chain may be optimized with respect to other properties than signal quality (e.g., power efficiency), while one or more auxiliary transmit chains may be used to enhance the signal quality of the final signal. | 12-04-2008 |
