Abstract
The effect of feedback delay error on adaptive digital predistortion is ana lysed, i.e. a linearisation technique for RF power amplifiers is developed. A method for calculating achievable adjacent channel interference level wi th certain delay error is presented. The method and results can be utilised in estimating the required accuracy for delay compensation.
