摘要：A method and apparatus for modeling distortion of a non-linear device aredisclosed. A pre-distorter model has a plurality of branches. Each branch receives adifferent output basis function signal. At least one branch includes a down-sampler, a
memory structure and an up-sampler. The down-sampler down-samples the receivedoutput basis function signal received by the branch by a factor of 1/M, where Misdifferent for each of the at least one branches. The memory structure includes at leastone delay element to delay the output of the down-sampler according to a
predetermined delay. The memory structure has an output based on an output of the atleast one delay element. The up-sampler up-samples the output of the memorystructure by the up-sampling factor, M.
