ABSTRACT:
The invention solves the problem of efficiently generating pseudo noise sequences with an arbitrary offset delay. Novel and improved architectures are used, based on the matrix-vector pseudo noise generators. A first embodiment of this invention includes a plurality of serially connected transition matrix multiplication circuits producing a plurality of output state matrices. A second embodiment of this invention combines a first stage having plurality of matrix multiplication circuits connected to a first multiplexer circuit which selects an state matrix or one of the matrix products with a serial chain of matrix generator circuits including second matrix multiplication circuit and a second multiplexer selecting either a first input or the output of the second matrix multiplication circuit.
