Mathews, V. John | A baseband residual vector quantization algorithm for voiceband data signals | Abstract-In this paper, we present a new approach to the digitization and compression of a class of voiceband modem signals. Our approach, which we call baseband residual vector quantization (BRVQ), relies heavily upon the simple structure present in a modem signal. After the signal is converted to... | 1989 | |

Mathews, V. John | Efficient FIR adaptive filter using DPCM and the sign algorithm | This correspondence introduces an adaptive filter structure that requires zero multiplications for its implementation. The primary input signal is quantized using DPCM, and the DPCM outputs are processed by a conventional adaptive filter. The filter coefficients are updated using the sign algorithm.... | 1989 | |

Mathews, V. John | Multiplication-free vector quantization using the L l distortion measure and its variants | Vector quantization is a very powerful technique for data compression and consequently, it has attracted a lot of attention lately. One major drawback associated with this approach is its extreme computational complexity. This paper first considers vector quantization that uses the L1 distortion mea... | 1989 |
