Estimate error compared with previous study. (a) The gain estimate error in different SNR. (b) The phase estimate error in different SNR. (i) are the results of LMS, (ii) are the results of MUSIC with 5 calibrated elements, (iii) are the results of MUSIC with 2 calibrated elements, (iv) are the results of ESPRIT with 5 calibrated elements, and (v) are the results of ESPRIT with 2 calibrated elements.
