e parameter for measuring the amount of the out-of-band distor-
tion of the power amplifier is the adjacent channel power ratio (ACPR)
or also known as the adjacent channel leakage ratio (ACLR), and it is
defined as the ratio of the total power over the channel bandwidth to
the power delivered in the adjacent channels (both upper sideband[US]
and lower sideband [LS]).
e following equation shows the formula for calculating ACPR
