Abstract
A multiple access scheme is provided. A first communications terminal encodes a first data stream using a forward error correction (FEC) code, and scrambles the encoded first data stream based on a first scrambling signature. A second communications terminal encodes a second data stream using the FEC code, and scrambles the encoded second data stream based on a second scrambling signature. The first scrambling signature and the second scrambling signature are used, respectively, by the first terminal and the second terminal to distinguish the first encoded data stream from the second encoded data stream as respectively originating from the first terminal and the second terminal in a multiple access scheme, whereby the first encoded data stream and the second encoded data stream simultaneously share a wireless communications channel. The FEC code is a low density parity check (LDPC) code configured with a data node degree of two or three.
