Latest Patents

Zhanwei Sun's latest patents include a "Method and apparatus for wideband spectrum sensing." This invention provides examples of wideband spectrum sensing techniques for cognitive radio, allowing for undersampling of the spectrum band. This approach enables the use of more cost-effective electronic components, such as lower frequency analog-to-digital converters (ADC). The techniques also facilitate the determination of available sub-channels for transmission, ensuring that only a portion of the spectrum band is sampled. Detection decisions are based on performance metrics tailored for wideband spectrum sensing, specifically the probability of insufficient spectrum opportunities and the probability of excessive interference opportunities.

Another significant patent is titled "Sequence detection methods, devices, and systems for spectrum sensing in dynamic spectrum access networks." This invention incorporates a hidden Markov model and a risk function to determine the primary user state sequence with minimal associated risk. The system includes weighted cost factors to differentiate between missed detection and false alarm sensing errors. Additionally, it features a complete forward partial backward computation designed to enhance sensing accuracy while minimizing delays and complexity.
