Abstract
A polar-based modulator includes an amplitude signal generator operating at a set gain and a command module that selects an appropriate one parameter lookup table based on an identification of the current network communication system. The command module receives a digital representation of the desired amplitude and using the received digital amplitude and selected parameter lookup table determines control commands used by a scalar to appropriately modulate an amplitude modulated signal output from the amplitude signal generator. Use of the parameter lookup table and command module in the digital realm eliminates the complexities of comparable functionality in the analog realm. Further, operating the amplitude signal generator at a set gain and scaling the output eliminates the complexities associated with generating an appropriately amplified signal within the amplitude signal generator and improves the overall efficiency for generating such an amplitude modulated signal.
