Title: METHOD FOR ADJUSTING POWER OF ANTENNA SIGNAL AND BASE STATION
Abstract:
Embodiments of the present invention relate to a method for adjusting the power of an antenna signal, comprising: a base station determining N first digital signals according to acquired N baseband digital signals, the power of the signals being the sum of the partial powers of each of four baseband digital signals, where N is a positive integer multiple of 4; obtaining, according to the N first digital signals, N first radio frequency analog signals having the same power as the corresponding N first digital signals, so as to acquire N second radio frequency analog signals, the power of the N second radio frequency analog signals being the sum of the powers in the N first radio frequency analog signals corresponding to the same baseband data signals in the N first digital signals, and the powers of the second radio frequency analog signals being the same as the powers of baseband digital signals corresponding thereto; and sending the second radio frequency analog signals by using an antenna, so that powers from a plurality of feed channels mutually converge and are sent to a same antenna, overcoming the problem of the limited rated power of a single feed channel and greatly increasing the power of a multi-antenna system.
