摘要

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 i^thdigital data corresponding to an i^threceiver 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 i^thdigital data and performing sliding correlation on the decimated data, and extracting attenuation and phase characteristics of the i^threceiver wired path by extracting samples after the time delay among the decimated samples.
