Fast and accurate ACLR estimation method
The paper presents theory and simple expressions to estimate adjacent-channel leakage power ratio (ACLR or ACPR) with WCDMA signals that greatly simplify the design of analog circuits. High accuracy is obtained when the AM/AM and AM/PM conversion can be modeled by a polynomial of reasonable order. Results based on a power amplifier and a low-noise amplifier give less than 1dB estimation error for
