- Abstract
- Provided is a method of correcting a time misalignment between envelope and phase components in a transmitting apparatus which separates envelope and phase components of a signal, processes them, and then recombines them to transmit the recombined signal. For this, in a method of correcting a time misalignment between envelope and phase components according to an embodiment of the present invention, a time misalignment is corrected by applying a time delay to at least one of envelope and phase components in digital and analog signal processing operations, or applying a time delay to an envelope or phase component by a pre-processing operation.
