Over-Complete Source-Mapping Aided AMR-WB MIMO Transceiver Using Three-Stage Interative Detection

Othman, N.S., El-Hajjar, M., Pham, A.Q., Alamri, O., Ng, S.X. and Hanzo, L. (2008) Over-Complete Source-Mapping Aided AMR-WB MIMO Transceiver Using Three-Stage Interative 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 Wideband (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 an Eb/N0 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 Isystem = 3 system iterations.
