METHOD AND APPARATUS FOR INTERLEAVING A DATA STREAM USING QUADRATURE PERMUTATION POLYNOMIAL FUNCTIONS (QPP) |
摘要 |
A semiconductor device comprising processing logic. The processing logic is arranged to configure interleaver logic to re-order data symbols of a data stream according to a quadrature permutation polynomial function. The processing logic is further arranged to: divide a cyclic group of values defined by the QPP function into a set of subgroups, the set of subgroups being capable of being defined by a set of linear functions; derive inverse functions for the set of linear functions defining the subgroups; and configure the interleaver logic to load the data symbols of the data stream into a buffer at locations within the buffer corresponding to a cyclic group of values representative of the inverse function for the QPP function based on the inverse functions of the set of linear functions defining the subgroups.
