Professor Simon S. Woo's research lab specializes in reliable and efficient data transmission, particularly in challenging environments such as space communications. The lab focuses on innovative coding techniques—especially Luby Transform (LT) codes—to prioritize critical data, ensuring high-priority information is decoded quickly and accurately. Their work emphasizes designing intelligent degree distributions in fountain codes to enhance decoding performance and reliability for mission-critical applications. The lab also explores cross-layer optimization and real-time adaptation in communication systems to improve overall system efficiency.

It is common in data transmissions that some information is more important than others. This is especially true in space communications where mission critical information or science data are high priority. In this work, we propose a simple yet constructive scheme to send high priority data reliably and efficiently using Luby transform (LT) codes. The new proposed scheme modifies the conventional LT encoder to send high priority data as a degree 1 and 2 so that high priority data can be quickly r
