According to the formed CD recording information, the principle of digital processing system, audio errorcorrectingcode and EFM technology is analyzed and explored.
Theory analysis and computer simulation results of throughput of S-ALOHA-DS/CDMA are obtained using different errorcorrectingcode. And comparison results with MC-S-ALOHA system are also obtained.
