Abstract
A method and apparatus for memory modeling in a pre-distortion architecture are disclosed. In one embodiment, a memory model has a plurality of branches. Each branch receives a different output basis function signal. Each branch includes at least one delay element. Each delay element causes a pre-determined delay of the output basis function signal received by the branch. The amount of a pre-determined delay is different for each of at least two branches.
