Voice coder/decoder and methods of coding/decoding

The Journal of the Acoustical Society of America, 1994
A new adaptive Fourier transform coder/decoder encodes periodic components of speech signals and decodes the encoded periodic components. The pitch frequency of voice signals in successive time frames at the voice coder may be determined as by (1) Cepstrum analysis (e.g.

Fast decoder of BCH code with cyclic decoding method

2016 International Siberian Conference on Control and Communications (SIBCON), 2016
Fast decoder of BCH code (31, 16, 7) which based on matrix algorithm of syndromes computation and parallel data processing was developed. Functional blocks of developed device based on block-based design were described. Device testing with coding and decoding modes and 50 MHz frequency was conducted.

Speech decoder and a method for decoding speech

The Journal of the Acoustical Society of America, 2009
A speech decoder comprises a decoder (103) for converting a linear prediction encoded speech signal into a first sample stream having a first sampling rate and representing a first frequency band. Additionally it comprises a vocoder (105) for converting an input signal into a second sample stream having a second sampling rate and representing a second ...

Compacted codeword Huffman decoding method for MPEG-2 AAC decoder

2013 IEEE International Conference on Consumer Electronics (ICCE), 2013
This paper proposes a new MPEG-2 AAC Huffman decoding algorithm which is designed to find multiple symbols in a single search. The analysis and experimental results show that the computational complexity of the proposed method is lower by more than 46% when compared with those of the up-to-date methods.

Voice encoding method and voice decoding method

The Journal of the Acoustical Society of America, 1996
A compressed digital speech signal is encoded to provide a transmission error-resistant transmission signal. The compressed speech signal is derived from a digital speech signal by performing a pitch search on a block obtained by dividing the speech signal in time to provide pitch information for the block.

Designing a high-throughput VLC decoder. I. Parallel decoding methods

IEEE Transactions on Circuits and Systems for Video Technology, 1992
For pt.I see ibid, vol.2, no.2, p.187, 1992, For applications in graphic computers, image and video composition, high-definition television (HDTV), and optical fiber networks, Huffman-coded images need to be reconstructed at a high throughput rate. Part I showed several architectural and architecture-specific optimization techniques.

Method of decoding telegraphic speech

The Journal of the Acoustical Society of America, 2005
A method of selecting a language model for decoding received user spoken utterances in a speech recognition system can include a series of steps. The steps can include computing confidence scores for identified closed-class words and computing a running average of the confidence scores for a predetermined number of decoded closed-class words ...

A shuffled message-passing decoding method for memory-based LDPC decoders

2009 IEEE International Symposium on Circuits and Systems, 2009
The convergence speed of shuffled message passing decoding (MPD) is faster than that of standard two phase message passing (TPMP) decoding. Due to complex memory access and requirement of large storage space, the shuffled MPD is not suitable for hardware implementation especially for high-rate LDPC codes.

An efficient FTN decoding method using separation Of LDPC decoding symbol

2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN), 2016
To increase throughput efficiency and improve performance, FTN (Faster Than Nyquist) method and LDPC (Low Density Parity Codes) codes are employed in DVB-S3 system. In this paper, we proposed efficient turbo equalization model to minimize inter symbol interference induced by FTN transmission.
