ABSTRACT:
A method and apparatus for normalizing the I and Q components of a complex signal is provided which includes an iterative determination of the multiplier constant required for normalization. The I and Q components are squared and added together to create a digital word A constrained between certain limits. An iterative approach is implemented to arrive at a multiplier constant K which is equal to ##EQU1## without resorting to the use of multipliers. The constant K is then used to normalize the I and Q components.
