2003 IEEE Wireless Communications and Networking, 2003. WCNC 2003., 2003•ieeexplore.ieee.orgThis paper presents an asynchronous interleave-division multiple-access (IDMA) scheme, in
which users are distinguished by different chip-level interleaving methods instead of by
different signatures as in a conventional code-division multiple-access (CDMA) scheme. A
very low-cost iterative detection algorithm is derived for the IDMA scheme based on a chip-
by-chip detection principle. The proposed scheme can achieve nearly optimal performance
for systems with a large number of users. Furthermore, receiver simplicity as well as high …

This paper presents an asynchronous interleave-division multiple-access (IDMA) scheme, in which users are distinguished by different chip-level interleaving methods instead of by different signatures as in a conventional code-division multiple -access (CDMA) scheme. A very low-cost iterative detection algorithm is derived for the IDMA scheme based on a chip-by-chip detection principle. The proposed scheme can achieve nearly optimal performance for systems with a large number of users. Furthermore, receiver simplicity as well as high performance can be maintained in multipath environments.
