We proposed a nonbinary byte-interleaved coded-modulation scheme with inner and outer turbo-like iterative decoder. The net coding gain is 0.6dB higher than the state-of-the-art binary SPC-LDPC-based turbo-product counterpart, with adjustable iterations and lower error-floor.
Separating redundancy, proposed by Abdel-Ghaffar and Weber, is an important concept in the analysis of the error and erasure decoding of a linear block code using a parity-check matrix of the code. In this paper, we investigate the second and third separating redundancies of extended Hamming codes. For an extended Hamming code, we establish two binary integer linear program problems, the optima of...
Transverse flux permanent magnet generator (TFPMG) has attracted a great attention for the large torque and high efficiency at low speed, as well as the prominent capability of carrying considerable pole numbers [1]. Many new TFPMGs with attractive structures have been proposed such as a novel flux switching transverse flux PM generator (FS-TFPMG) presented to improve the stator space utilization...
Transverse flux permanent magnet generator (TFPMG) is especially suitable for wind power application for the merits of large pole numbers, decoupled magnetic circuit, and high power density. The distinguishing feature of TFPMG is the magnetic flux existed in three-dimensional space and three-dimensional finite element method (3-D FEM) is employed to analyze its characteristics. Such as flux-switching...
Many problems are existed in complex technology system, and the relationships among them are complicated and interweaved. In order to solve these problems innovatively, a systematic analysis and accurate description is a must for the initial problem situation. Only the problems were extracted precisely, can they be settled efficiently. The pyramidal model, a form of problem flow networks, is built...
We successfully transmitted 100GHz-grid, 20 channels single-carrier 440-Gb/s super-Nyquist signal over 3600km. Record all-ETDM-based 110-GBaud PDM-QPSK is coherently detected by a real-time oscilloscope at 160 GSa/s with 65-GHz bandwidth, achieving a net SE of 4b/s/Hz.
A new single-sample failure model for a CNC system, whose operation has been followed up by the authors for a period of over two years, is proposed in this paper. A reliability database has been created to collect all the failure data, from which the main source of failures can be identified. The Bayesian method is used for the reliability evaluation and the weighted least squares method is used for...
All-optical up-conversion based on dual-pump four-wave mixing (FWM) in 2-m Bismuth Oxide-based fiber for 10-Gb/s OOK wireless signals in 60-GHz ROF systems has been experimentally demonstrated for the first time.
We experimentally demonstrate all-optical up-conversion of radio-over-fiber signals based on a dual-pump four-wave mixing in an semiconductor optical amplifier for the first time. 2.5 Gbit/s baseband signals are successfully up-converted to 40-GHz millimeter-wave carrier.
In this paper, multiple-symbol differential detection (MSDD) for space-time block codes (STBC) is considered over fast Rayleigh fading multiple-input multiple-output (MIMO) channels. The decision metric is derived by considering the fading autocorrelation, and the M-algorithm is adopted to reduce the computational complexity of the decision metric. Simulation results demonstrate that MSDD is effective...
