System and method for monitoring adjacent channel power in a wireless base station |
摘要 |
There is disclosed an ACP monitoring circuit for use in a wireless network comprising a plurality of base stations for communicating with a plurality of mobile devices. Each of the plurality of base stations comprises an RF transmitter that receives an input baseband signal and an RF carrier signal and produces a modulated RF output signal that is then amplified. The ACP monitoring circuit monitors adjacent channel power (ACP) noise in the RF output signal. The ACP monitoring circuit comprises: 1) an RF mixer having a first input receiving the RF output signal and a second input receiving the RF carrier signal and produces a scaled output signal on an output of the RF mixer; and 2) a first power detection circuit coupled to the RF mixer output that determines a power level of the ACP noise outside an allocated channel bandwidth of the RF transmitter.
