adjacent channel power ratio (ACPR)

Inmobile radio measurement technology, there are several parameters that can be used to determine the performance of mobile radio systems. Adjacent Channel Power Ratio (ACPR) is one such parameter.

Adjacent Channel Power Ratio (ACPR) is the neighbor power ratio measured directly at the transmitter output, which can be used to detect filter problems. The ACPR measurement determines the adjacent channel power ratio. The power of adjacent channels is compared to that of the main channel and expressed in decibels( dB).

The Adjacent Channel Power Ratio (ACPR) has been referred to as Adjacent Channel Leakage Ratio( ACLR) or adjacent channel leakage for some time.
