Abstract:

A method and apparatus for interleaving and deinterleaving pseudo-randomly a digital signal which is transmitted over a transmission channel is disclosed. A received bit stream is interleaved such that the order of the bits is varied in a non-random manner. The order of the interleaved bits is permutated in a pseudo-random manner and the bits are then transmitted over a transmission channel. The received bits are inverse permuted so as to return the order of the received bits to the order of the bits after the non-random interleaving step. The inverse permuted bits are then deinterleaved in the reverse order in which they were interleaved so as t reconstitute the original bit stream. Author
