A High Performance and Bandwidth Efficient IDMA Scheme with Large Receiver MIMO Technologies

Interleave Division Multiple access (IDMA) is a new multiple access scheme, and Multiple-Input Multiple-Output (MIMO) is an emerging technology in the wireless broadband communications. In this paper, we investigate the performance of the IDMA scheme with Large Receiver MIMO (LR-MIMO) with different antenna configurations for the multiuser detection. The bit error rate (BER) performance of the proposed system is analyzed for different channel conditions. Numerical results show that the LR-MIMO-IDMA scheme provides superior performance with the aid of MIMO detection techniques over frequency selective fading channel. Also, this scheme further enhances bandwidth efficiency by reducing the repetition length of the IDMA scheme.
