Title: Innovations by Chamroeun Kchao
Introduction
Chamroeun Kchao is a notable inventor based in San Jose, CA (US). He has made significant contributions to the field of satellite communications, holding a total of 4 patents. His work focuses on enhancing the efficiency and effectiveness of satellite data transmission.
Latest Patents
One of his latest patents is a "Concatenated coding system for satellite communications." This invention provides a method for custom coding uplink signals and downlink beams in a satellite communications system. The method involves applying an outer code at a ground station to produce an outer coded uplink signal. The ground station then applies a selected reduced complexity inner code to this signal, resulting in a concatenated coded uplink signal that is transmitted to a satellite. The satellite decodes the inner code to produce an outer coded satellite data stream, which is further processed before being transmitted back to a destination ground station.
Another significant patent is "Satellite communication adaptive control coding." This method maximizes the satellite downlink information rate. It involves a ground transmitter applying an outer block code to a data channel, which is then modulated and transmitted to a satellite. The satellite demodulates the uplink data stream and produces a demodulated uplink data stream consisting of multiple user channels. The method utilizes multiplexers and quality encoders to produce custom-coded data signals, which are then transmitted back to a ground receiver.
