Coding of quantization matrices using parametric models
Quantization matrix can be used to adjust quantization of transform coefficients at different frequencies. In one embodiment, a single fixed parametric model, such as a polynomial is used to represent a quantization matrix. Modulation of bit cost and complexity is achieved by specifying only the n first polynomial coefficients, the remaining ones being implicitly set to zero or other default values. One form of the single fixed polynomial is a fully developed polynomial in (x, y), where x, y indicate the coordinates of a given coefficient in a quantization matrix, with terms ordered by increasing exponent. Since higher exponents are the last ones, reducing the number of polynomial coefficients reduces the degree of the polynomial, hence its complexity. The polynomial coefficients can be symmetrical in x and y, and thus reducing the number of polynomial coefficients that need to be signaled in the bitstream. |

Retransmission of selected PAM-modulated message portions in 5G/6G
When a received message is found to be corrupted in 5G or 6G, the receiver can request a retransmission. If only one message element is faulted, retransmitting the whole message may be a waste.

Impedance controlled electrical interconnection employing meta-materials
A method of improving electrical interconnections between two electrical elements is made available by providing a meta-material overlay in conjunction with the electrical interconnection. The meta-material overlay is designed to make the electrical signal propagating via the electrical interconnection to act as though the permittivity and permeability of the dielectric medium within which the electrical interconnection is formed are different than the real component permittivity and permeability of the dielectric medium surrounding the electrical interconnection. In some instances the permittivity and permeability resulting from the meta-material cause the signal to propagate as if the permittivity and permeability have negative values. Accordingly the method provides for electrical interconnections possessing enhanced control and stability of impedance, reduced noise, and reduced loss. Alternative embodiments of the meta-material overlay provide, the enhancements for conventional discrete wire bonds whilst also facilitating single integrated designs compatible with tape implementation. |
