Hccc and Slbc for Audio Signals
نویسنده
چکیده
This paper gives two lossless speech compression schemes Hamming correction codes compressor (HCCC) and Systematic Linear Block Code Compressor (SLBC) based on error correcting Hamming code and systematic linear block codes respectively. Hamming codes are a family of linear errorcorrecting codes that can detect up to two-bit errors or correct one-bit errors. Systematic linear block code is any error correcting code in which the input data is embedded in the encoded output. Systematic codes have the advantage that the parity data can simply be appended to the source block, and receivers do not need to recover the original source symbols if received correctly. The performance of the HCCC (Hamming correction code compressor) has been analyzed for different parity numbers of 3, 4, 5. Also the HCCC compressor performance is compared with Systematic Linear Block Code compressor (SLBC).

متن کاملDesign of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...

In this paper, we present a Compressive Sampling (CS)-based feature extraction method for audio signals. In the proposed approach, the audio signal is firstly segmented by hamming windows and the Discrete Fourier Transform (DFT) of the samples is calculated within each frame. Then, the normalized values of the DFT coefficients of each frame are accumulated. At the next step, the second DFT is a...
