Abstract
This paper presents comprehensive comparisons of interleave division multiple access (IDMA) and Code division multiple access (CDMA) in terms of performance and complexity using iterative multiuser detection technique. It also exploits the interleaving as only means of user separation instead of by different signatures as in a conventional code division multiple-access (CDMA) scheme. The given scheme can achieve near single user performance in situations with very large numbers of users while maintaining very low receiver complexity. This technique shows that high performance can be maintained in multi-path environments. IDMA inherits many advantages from CDMA, such as diversity against fading and mitigation of the worst-case user interference problem. We also discuss several aspects of complexities for IDMA and DSCDMA when the MMSE detector is used. Computer simulations are performed in various scenarios and the performance is analysed by bit error rate as well as by extrinsic information transfer chart. The analysis reveals some advantages of IDMA over CDMA, particularly in highly user loaded scenarios
