Latest Patents

Zaltsman's latest patents include significant advancements in the field of signal processing. One of his inventions is the "Normalization of equalizer soft output for channels with varying noise power." This apparatus and method generate normalized soft decision information output from an inner decoder in a communications receiver. The invention normalizes the soft decision information before it enters a soft outer decoder, utilizing a dynamically calculated noise power estimate in response to changing noise statistics on the channel. This process ensures maximum performance from the soft outer decoder by applying a binary or smoothly weighted average based on performance metrics such as the Signal to Noise Ratio (SNR).

Another notable patent is the "Whitening matched filter for use in a communications receiver." This innovative filter is constructed by cascading a matched filter and a noise-whitening filter. The matched filter's response is derived from the time-reversed complex conjugate of the channel impulse response, while the whitening filter is created by extracting the minimum phase portion of the mixed phase channel impulse response using homomorphic deconvolution. This design allows for effective processing of data received before and after the training sequence.
