Abstract
Shift-keying specific CS DOA estimation requires accuracy guarantees of CS recovered phase and magnitude estimates before being used as input information for the sub-space DOA estimation algorithms. Otherwise, if accuracy of phase and magnitude estimates cannot be guaranteed, the use of CS sampled and recovered information for DOA estimation will fail. Only when the accuracy guarantees are determined for shift-keying specific CS recovery, can we proceed to utilize CS recovered phase, magnitude, and BIE estimates as scalar inputs to sub-space DOA estimation algorithms.
