Abstract
An interleaver parameter generator circuit used to calculate and generate on an as needed basis interleaver parameters for interleaving blocks of information of varying lengths in accordance with a pseudorandom pattern defined by the 3GPP standard. The interleaver parameter generator circuit calculates and generates the defined interleaver parameters based on an input parameter that represents the length of the block of information to be interleaved. At least one of the defined parameters is calculated and generated using a decomposed form of its definition. The interleaver parameter generator circuit uses well known circuit blocks such as multipliers, subtractors, Compare-and-Select circuits and other circuits to calculate and generate the defined parameters.
