In mobile radio measurement technology, there are several parameters that can be used to determine the performance of mobile radio systems. Adjacent ChannelPower
Ratio (ACPR) is one such parameter. Adjacent Channel Power Ratio (ACPR) is the adjacent power ratio that is measured directly at the transmitter output and can be used to detect filter problems. The ACPR measurement determines the adjacent channel power ratio.
The Adjacent Channel Power Ratio (ACPR) has been referred to as Adjacent Channel Leakage Ratio (ACLR
) for some time.
