Interleaving-Based Multiple Access and Iterative Chip-by-Chip Multiuser Detection
Wai Kong Leung, Lihai Liu, Li Ping · 2003
This letter examines a very simple iterative chip-by-chip multiuser detection strategy for spread spectrum communication systems. An interleaving-based multiple-access transmission technique is employed to facilitate detection. The proposed scheme can achieve near single-user performance in situations with very large numbers of users while maintaining very low receiver complexity. Key words: CDMA, multiple access interference, multiuser detection, turbo detection. 1.
