ABSTRACT:
Methods and apparatus for generating and performing digital communications using a randomized generatable interleaver. In accordance with one exemplary embodiment of the invention, a pseudo random interleaver of size n*m with excellent randomness and spread properties may be generated from a set of seed values. The interleaver of size N=n*m is defined by dividing the N possible address in the interleaver (0-N−1) into n subsets. The subsets are preferably generatable from a single value within the subset either using an algorithm or a memory based lookup table. The set of n seeds comprises one value selected from each subset. An improved communication system incorporating the aforementioned interleaver and using turbo codes or other concatenated coding systems is also disclosed.
