Title: Desmond Wai Yan: Innovator in Digital Communication Technologies
Introduction
Desmond Wai Yan is a notable inventor based in Vancouver, Canada. He has made significant contributions to the field of digital communication technologies, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Digital Diversity Receiver System." This invention features a two-way paging system that includes multiple transmitters and receivers, along with at least one two-way personal paging unit. The system allows for the transmission of pages from the transmitter, while the pager sends response signals detected by the receivers. These response signals are formatted as digital packets, which include forward error correction encoding and digital symbols. The system enhances reliability by using 'accuracy indicators' associated with detected symbols, allowing for improved detection and decoding of pager responses.
Another significant patent is the "Method and Apparatus for Linear Transmission by Direct Inverse Modeling." This system focuses on linearly transmitting an amplified output signal using predistortion. It employs a straightforward inverse modeling scheme to accurately determine the inverse of distortion caused by a power amplifier in an RF transmitter. By modeling the power amplifier as a signal processing block with reversed input and output ports, the system avoids the computationally intensive inversion required by conventional methods. This innovative approach allows for more efficient compensation of power amplifier distortion.
