CDMA/OFDM Compliant Wireless Communication from a Non-Linear Finite Impulse Response Filter Configured with Coefficients that are Responsive to an Input Signal Magnitude

摘要

A digital pre-distortion system which can provide the flexibility to model the highly non-linear distortion associated with High Efficiency RF Power Amplifiers while through a novel implementation of a least squares estimation process allows an implementation well suited for an FPGA application where limited resources and in particular memory resources are available.
