METHOD, APPARATUS AND SYSTEM FOR CALIBRATING CHANNEL |
摘要 |
A method for calibrating a channel which includes: performing slide-window correlation on a delayed downlink service signal of a current transmit channel and a feedback signal of the transmit channel, and performing sampling to obtain a group of correlation values of the transmit channel in a sliding window; determining a peak amplitude value among amplitude values of the group of correlation values in the sliding window, and amplitude values at two points that are left adjacent and right adjacent to a point corresponding to the peak amplitude value; performing an interpolation operation on the peak amplitude value and the amplitude values at the two points that are left adjacent and right adjacent to the point to obtain an amplitude value, a delay and a phase at an actual peak point in the group of correlation values of the transmit channel in the sliding window; and calibrating the transmit channel.
