Abstract
The method includes performing a wired back-to-back test by forming M wired paths connecting one of the N transmission antennas with the M reception antennas through M cables, separating idigital data corresponding to an ireceiver wired path from the plurality of digital data stored in the receiver wherein i is a natural number greater than 1 and smaller than M, extracting a time delay by decimating the separated idigital data and performing sliding correlation on the decimated data, and extracting attenuation and phase characteristics of the ireceiver wired path by extracting samples after the time delay among the decimated samples.
