Complex CORDIC-like algorithms for linearly constrained MVDR beamforming

In this paper we investigate the use of CORDIC-like approximate rotations for complex valued signal processing applications. In particular we design a processor array for minimum variance distortionless response (MVDR) beamforming with multiple constraints entirely based on linear and circular complex transformations. The required transformations are expressed as factorized transformations such that they can be represented as sets of real CORDIC-like modules.
