چکیده

This paper outlines the operational concepts of recently proposed Interleaved Division Multiple Access (IDMA) scheme. Some interesting features of Interleaved Division Multiple Access (IDMA) over conventional Code Division Multiple Access (CDMA) are explained including its performance, simple receiver structure as well as spectral efficiency. The basic principle of IDMA is that interleaver is different for each user whereas CDMA employs different signatures. IDMA inherits many advantages of CDMA such as robust against fading, easy cell planning and dynamic channel sharing. Further IDMA increase the spectral efficiency and reduce the receiver complexity. General Terms Spectral efficiency, PN Sequences
