Abstract
An apparatus and method for reducing unwanted spectral emissions of a complex signal to be transmitted comprising calculating the nth power of the complex signal to be transmitted, calculating the complex conjugate of the nth power of the complex signal to be transmitted, applying a scaling factor to the complex conjugate to form a scaled correction signal, and adding the scaled correction signal to the signal to be transmitted.
