Embodiment Construction
[0054] In order to further explain the technical means and functions adopted by the present invention to achieve the intended purpose, the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0055] In related technologies, in order to maintain the phase synchronization state between the channels of the base station, most base stations adopt a common local oscillator scheme, such as figure 1 shown. The base station system of the common local oscillator scheme is composed of the same clock generator 122 , PLL (local oscillator generator) 101 , local oscillator distributor 102 and amplifier circuits 103 , 109 , and 114 .
[0056] The biggest feature of the common local oscillator scheme is that the local oscillator signals of all the transceiver channels of the whole machine come from the same local oscillator generator 101, thus ensuring that the phases reaching the mixers of each channel are the same, as...
