Introduction

Don Li is a prominent inventor based in Morganville, NJ (US). He has made significant contributions to the field of telecommunications, particularly in the development of advanced communication systems. With a total of 7 patents to his name, Li's work has paved the way for innovative solutions in data transmission.

Latest Patents

One of Li's latest patents is a multi-channel spread spectrum system. This system effectively separates a data stream into sub-channel data-sequence signals. For each sub-channel, m bits are translated into a unique set of orthogonal chip-sequence signals, while the remaining k bits are converted into distinct phasors. These phasors modulate the respective chip-sequence signals, which are then combined into in-phase (I) and quadrature (Q) spread-spectrum multi-channel signals. The system supports a constant data rate throughout the cell by maintaining a large processing gain, allowing for efficient deployment of a code-reuse-one type spread-spectrum system.

Another notable patent is the power-controlled random access method. This innovative approach enables mobile stations to quickly access base stations. A composite power control command is generated at the mobile station after an initial access attempt. This command utilizes both open-loop and closed-loop power-control symbols to determine the mobile station's next actions. The mechanism helps resolve collisions between mobile stations and maintains low delay in the random-access process.
