ABSTRACT:
Simplified method and apparatus for performing integrated scrambling and encoding or descrambling and decoding of block code digital transmissions is disclosed. The method involves setting the scrambling length equal to an integer multiple of the block length, and then implementing a pseudorandom number sequence generator within the block length counter. The output of the pseudorandom number sequence generator is then logically combined with the incoming data to provide scrambled data, simplifying the complexity of the encoder or decoder significantly.
