Latest Patents

Siller holds a patent titled "Fractionally spaced equalization using Nyquist-rate coefficient updating." This invention describes a fractionally spaced adaptive equalizer that updates coefficients synchronously through an integral -T error circuit and alternately via a fractional =T error circuit. This innovative arrangement ensures a unique minimum for the adaptive structure, preventing coefficient drift to excessively large values. Consequently, coefficient tap leakage is not necessary to minimize coefficient values. The adaptive characteristics of this invention are particularly well-suited for linearly dispersive channels, such as those encountered during terrestrial radio transmission amid tropospheric multipath propagation. The principles of this invention are broadly applicable to various well-known algorithms for adapting digital filters. Additionally, a configuration of fractionally spaced equalizers provides the advantages of Nyquist-rate coefficient updating for dual rail quadrature amplitude modulated (QAM) signal applications.
