This paper describes a concept of non-adaptive Digital Feed-forward Linearization. A feed-forward amplifier is a system designed to reduce the spectrum re-grows appearing due to the amplifier’s nonlinearity. There are several general techniques to reduce nonlinearity effects. They are divided into two major groups. One of them (called “predistortion”)...
