Solution of a Complex Least Squares Problem with Constrained Phase.

Mark Bydder1.   

Abstract

The least squares solution of a complex linear equation is in general a complex vector with independent real and imaginary parts. In certain applications in magnetic resonance imaging, a solution is desired such that each element has the same phase. A direct method for obtaining the least squares solution to the phase constrained problem is described.
