Claim Text:
1. A method comprising: scrambling a first bit stream from a first terminal according to a first scrambling signature; and scrambling a second bit stream from a second terminal according to a second scrambling signature, wherein the first bit stream and the second bit stream are encoded using a low rate forward error correction (FEC) code generated based on polynomials configured to optimize performance in a multi-user-terminal system, wherein the encoding of each of the first and second bit streams is performed to output a composite signal using turbo code encoding, wherein the encoding utilizes constituent encoding having a transfer function: and wherein the use of the first scrambling signature for the first bit stream and the second scrambling signature for the second bit stream serves to distinguish the first bit stream of the first terminal from the second bit stream of the second terminal to provide a multiple access scheme.
