Tensor product and perfect shuffling for bit matrix transpose: Bit-interleaver for SDR DVB-T2

In this work, we explore the design-space with tensor product based representation for various blocked based bit-interleavers for software defined radio. An example application is to transpose of low aspect-ratio (width over height) bit-matrix, which is adopted in Second Generation Terrestrial Digital Video Broadcasting (DVB-T2) standard. We target software radio platforms supporting perfect-shuffling and data-packing instructions. We adopt a design procedure that presents the interleaver and the supported instructions with perfect-shuffling and tensor product; decompose the targeting interleaver into instructions in tensor product notation; explore the design space, and select for the best solution available. We demonstrate the method to be applicable to bit-operations by building the solutions on Texas Instruments c6416 CCS cycle accurate simulator. The simulation results and the design choices are discussed.
