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