Synthesis of bandlimited signals with independent amplitude and phase modulation

The synthesis of a bandpass bandlimited signal with independent AM and PM channels is considered, where the bandwidth of each of the two information signals is required to be less than or equal to half the bandwidth of the bandpass signal. A simple iterative algorithm for generation of the bandpass signal is proposed, and sample results are presented. It is shown that this approach may be useful in simultaneous amplitude phase transmission systems even when the number of iterations is small.
