In this paper1, we present a novel beam-search decoder for disfluency detection. We first propose node-weighted max-margin Markov networks (M3N) to boost the performance on words belonging to specific part-of-speech (POS) classes. Next, we show the importance of measuring the quality of cleaned-up sentences and performing multiple passes of disfluency detection. Finally, we propose using the be...

In this paper, by using MATLAB/Simullink software, Xilinx System Generator, Xilinx Alliance tools, Xilinx XSE & ISE and Modelsim XE software, a real-time transceiver platform is built up to analyze and verify the effectiveness and usability of the implemented FPGA-based DAB (Digital Audio Broadcasting) channel decoder. This hardware-level testing platform is completely conforming to DAB specifi...

We present an iterative channel estimation and decoding scheme for a coded system through multi-input multioutput (MIMO) Rayleigh block fading channels in spatially correlated noise. An expectation-maximization (EM) algorithm is utilized to find the maximum likelihood (ML) estimates of the channel and the spatial noise covariance matrix, based on which the soft information of coded symbols is c...

Presented in this paper is a pipelined 285-MHz maximum a posteriori probability (MAP) decoder IC. The 8.7-mm IC is implemented in a 1.8-V 0.18m CMOS technology and consumes 330 mW at maximum frequency. The MAP decoder chip features a block-interleaved pipelined architecture, which enables the pipelining of the add-compare-select kernels. Measured results indicate that a turbo decoder based on t...

This article investigates efficient blind watermark decoding approaches for hidden messages embedded into host images, within the framework of additive spread spectrum (SS) embedding based for data hiding. We study SS embedding in both the discrete cosine transform and the discrete Fourier transform (DFT) domains. The contributions of this article are multiple-fold: first, we show that the conv...

A new cellular structure for a versatile Reed-Solomon (RS) decoder is introduced based on time domain decoding algorithm. The time domain decoding algorithm is restructured to be suitable for introducing the cellular structure. The main advantages of this structure are its versatility and very simple cellular structure. By versatile decoder we mean a decoder that can be programmed to decode any...

An insight on the lattice decoder for flat-fading multiple antenna wireless communications systems is presented in this paper. In particular, we show that by formulating the decoding problem as a bounded-error subset selection, the resultant decoder finds the nearest lattice point to the received signal vector such that the search is bounded inside a hypercube centered at the received vector. T...

This paper proposes a method for hierarchical phrase-based stream decoding. A stream decoder is able to take a continuous stream of tokens as input, and segments this stream into word sequences that are translated and output as a stream of target word sequences. Phrase-based stream decoding techniques have been shown to be effective as a means of simultaneous interpretation. In this paper we tr...
