Digital predistortion technology is widely used in wireless communication. As a vital part of communication system, the radio frequency power amplifier has always been hot and difficult topic. This paper will research explore key technologies channel construction navigation information through artificial intelligence neural network. The article first conducts simple on new generation systems--a...

While digital predistortion (DPD) usually targets only the linearity performance of radio–frequency (RF) power amplifier (PA), this work addresses more than a single PA metric exploiting multi-objective optimization approach. We present predistorer learning procedure based on constrained algorithm that maximizes RF output power, while guaranteeing prescribed level, i.e., maximum normalized mean...
