PROBLEM TO BE SOLVED: To provide a method for improving a carrier to noise ratio in a receiver provided with diversity, and to provide a related apparatus. SOLUTION: The method and the system comprise a measure to extract the noise elements in signals to be demodulated through phase-shift, a measure to optimize the negation of useful elements via a return loop for processing a phase-shifter, and a measure to add the noise element for improving the carrier to noise ratio in same phase as the signal and also to add in the reversed phase.
