Interleave-Division Multiple-Access Based Broadband Wireless Networks

This paper studies the interleave-division multiple-access (IDMA) based broadband wireless network and its MAC protocol for supporting high data rates. The performance is evaluated by evolution and simulation. It is demonstrated that the IDMA technology can efficiently mitigate the interference among users and support high data rates without compromising the required quality of service. The results also demonstrate that multi-user gain can be achieved in IDMA systems where each user has a rate constraint. This means that given the same sumrate, the more number of users in a system is, the less average transmitted power per user is required.
