Latest Patents

One of Qiang Li's latest patents is titled "Noise detection for multi-channel and multi-protocol communications." This patent discloses techniques for quickly and accurately determining whether a channel is being used for data transmission across various communications protocols. The methods aim to improve sensitivity and reduce the false alarm rate across a wide range of signal and noise levels. An adaptive window size is utilized for fast noise detection, which increases the rate of scanning channels during a signal identification period. In a BLE1M detection mode, the detection of clusters of zero frequency deviation helps to minimize the false detection rate. Additionally, adaptive Zigbee symbol detection enhances detection sensitivity beyond −97 dBm. The techniques leverage chip-based differentials to generate frequency deviation samples for Zigbee detection, or data filtering frequency deviation samples based on an oversampled received signal to improve the signal-to-noise ratio.
