ABSTRACT:
A method and apparatus for correcting the phase and gain of data associated with a constellation pattern of a plurality of received individual symbols. Each symbol is divided into real and imaginary symbol components. The signs of the real and imaginary symbol components of each symbol are determined and used as a basis for determining whether the symbol is associated with a first or third quadrant of the constellation pattern or a second or fourth quadrant of the constellation pattern. The absolute values of the real and imaginary symbol components are determined and used to create a first sum and a second sum. A phase adjustment value θ and a gain adjustment value G are derived from the first and second sums, and are used to create a complex number. Each of the received individual symbols is multiplied by the created complex number to provide corrected constellation pattern data.
