Performance Analysis of Iteratively Detected and SVD- assisted MIMO-BICM Multimode Transmission Schemes

چکیده
In this contribution a coherent (2x2) (multiple input multiple output) MIMO transmission with iterative detection over a measured multimode fiber channel at 1325 nm operating wavelength is studied. For the channel measurements a fibre length of 1,4 km was chosen. Extrinsic information transfer (EXIT) charts are used for analyzing and optimizing the convergence behaviour of the iterative demapping and decoding. Our results show that in order to achieve the best bit-error rate, not necessarily all MIMO layers have to be activated.

Space-Time Block Coded (STBC) In-phase Quadrature-phase (IQ)-interleaved Coded Modulation (CM) schemes are proposed for Orthogonal Frequency Division Multiplexing (OFDM). Trellis Coded Modulation (TCM), Turbo TCM (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iteratively Decoded BICM (BICM-ID) schemes having a similar decoding complexity are employed in conjunction with 16-level Quadrature...

Maximum spatial-frequency diversity can be achieve by combining bit-interleaved coded modulation (BICM), orthogonal space-time block coding (OSTBC) and orthogonal frequency division multiplexing (OFDM) in frequency selective multi-path fading channels, provided that perfect channel state information (CSI) is available to the receiver. In view of the fact that perfect CSI can be obtained only if...

In this contribution the number of activated MIMO layers and the number of bits per symbol along with the appropriate allocation of the transmit power and the rate of the BICM error correcting codes are jointly optimized under the constraint of a given fixed data throughput. The performance investigations are carried out by computer simulations and confirmed by the EXIT charts. Our results show...
متن کاملPerformance Analysis of SVD-assisted Downlink Multiuser MIMO Systems
Abstract: Multiuser multiple-input multiple-output (MIMO) downlink (DL) transmission schemes experience both multiuser interference as well as inter-antenna interference. Instead of treating all the users jointly as in zero-forcing (ZF) multiuser transmission techniques, the investigated singular value decomposition (SVD) assisted DL multiuser MIMO system takes the individual user’s channel cha...

A Radial Basis Function (RBF) assisted reduced complexity In-phase/Quadrature-phase (I/Q) Turbo Equalisation (TEQ) scheme is investigated in the context of Trellis Coded Modulation (TCM), Turbo TCM (TTCM), Bit-Interleaved Coded Modulation (BICM) and iteratively decoded BICM (BICM-ID).
