Title: The Innovations of Edmond Y. Ho

Introduction

Edmond Y. Ho is a notable inventor based in Colts Neck, NJ (US). He has made significant contributions to the field of data communication, holding a total of 3 patents. His work primarily focuses on methods and apparatuses that enhance the efficiency and reliability of data transmission.

Latest Patents

One of his latest patents is an "Interference cancellation method and apparatus." This invention involves generating weighted sums of samples from an interference-corrupted data signal to create phase-compensated, symbol-spaced samples. The method includes conventional adaptive equalization and processes the signal to form tentative decisions regarding the transmitted data. Cancellation signals are generated to represent the interference components, which are then combined with the phase-compensated samples to produce final data decisions. The adaptive updating of weighting coefficients is based on error signals derived from the differences between cancelled samples and final decisions.

Another significant patent is related to "Equalizer sample loading in voiceband data sets." This invention is designed for a multipoint data communication system utilizing quadrature-amplitude modulation. It describes a master modem that connects with multiple tributary modems through various transmission channels. The adaptive equalizer circuitry in the master modem equalizes the channel from a specific tributary by multiplying received signal samples with tap coefficients stored in memory. The timing-acquisition circuitry adjusts the phase of the sampling circuitry to ensure accurate signal sampling at the start of transmission.
