Over-complete source-mapping aided AMR-WB MIMO transceiver using three-stage iterative detection

Othman, NS, El-Hajjar, M, Pham, AQ, Alamri, O, Ng, SX and Hanzo, L (2008) Over-complete source-mapping aided AMR-WB MIMO transceiver using three-stage iterative detection At IEEE ICC'08, China. 19 - 23 May 2008. , pp. 751-755.

Record type: Conference or Workshop Item (Paper)


In this paper we propose an iteratively detected Sphere Packing (SP) aided Differential Space-Time Spreading (DSTS) scheme using a Recursive Systematic Convolutional (RSC) code, for protecting the soft-bit assisted Adaptive Multi Rate Wide-band (AMR-WB) decoder's bitstream, which is also protected by a novel over-complete source-mapping scheme. The convergence behaviour of the Multiple-Input Multiple-Output (MIMO) transceiver advocated is investigated with the aid of both three-dimensional (3D) and two-dimensional (2D) Extrinsic Information Transfer (EXIT) charts. The proposed system exhibits E-b/E-0 gain of about 2.5 dB in comparison to the benchmark scheme carrying out iterative source- and channel-decoding as well as DSTS aided SP-demodulation, but dispensing with the over-complete source-mapping, when using I-system = 3 system iterations.
