Title: Hanan Herzberg: Innovator in Communication Systems
Introduction
Hanan Herzberg is a notable inventor based in Morganville, NJ (US), recognized for his contributions to communication systems. He holds a total of 7 patents, showcasing his innovative approach to technology and problem-solving in the field.
Latest Patents
One of Herzberg's latest patents is titled "System and method for providing near optimal bit loading in a discrete multi-tone modulation system." This invention discloses a communication system that transmits information using Discrete Multi-Tone (DMT) modulation. The system includes logic to measure the response of each DMT subchannel and adapt an equalizer filter based on these measurements. Additionally, it measures noise variance for each subchannel, allowing for optimal bit assignment to minimize total transmit power while maintaining a fixed data rate. Equations are provided for calculating near-optimal bit load allocation for the DMT subchannels.
Another significant patent is "System and method for concatenating Reed-Solomon and trellis codes." This apparatus concatenates Reed-Solomon and trellis encoders, receiving a plurality of information bits divided into two portions. The Reed-Solomon encoder processes the second portion, generating a first encoded output, which is then fed into a trellis encoder to produce a second encoded output. A mapper generates output signals uniquely defined by the input bits, ensuring larger Euclidean distances for the first portion compared to the second.
