Introduction

Hoang Nguyen is a prominent inventor based in Davis, CA, known for his significant contributions to wireless communication technologies. With a total of 4 patents to his name, Nguyen has made strides in developing advanced systems that enhance communication efficiency and reliability.

Latest Patents

Nguyen's latest patents include innovative technologies such as adaptive multi-beamforming systems and methods for communication systems. This wireless communication system features receiving and base stations, where the receiving station includes a detector that measures a downlink channel correlation matrix for multiple antennas of a base station. The detector computes an antenna weight increment vector normal to an antenna weight vector for multiple beams from the multiple antennas of the base station. Additionally, the detector quantizes the antenna weight increment vectors to produce a respective quantized antenna weight increment vector. The receiving station also includes a transmitter that sends these quantized vectors to the base station, which then utilizes a beamformer selector to re-orthogonalize the quantized antenna weight increment vector for each beam. Another notable patent is the Kalman filter-based method and apparatus for linear equalization of CDMA downlink channels. This invention discloses a minimum mean square error (MMSE) equalizer and method for single-user detection of a signal received from a downlink code-division multiple access (CDMA) channel. The equalizer incorporates a Kalman filter that generates a best linear unbiased estimate of a transmitted chip sequence for a single user.
