Abstract
Devices and methods for reducing and/or substantially preventing nonlinearities and discontinuities during the translation stage from an I/Q signal into a polar coordinate OFDM signal are provided. By way of example, a method includes receiving an incoming data signal via a processor of a transmitter. The method further includes computing one or more roots of a first function representing a phase component of the data signal, computing a second function representing the phase component, and deriving one or more characteristics of the phase component based on the second function. The method further includes adjusting one of the one or more characteristics in a second domain to establish a substantially finite bandwidth of the phase component.
