Latest Patents

One of Tang's latest patents is the Sub-thermal Spread Spectrum Data-Link. This innovative technology demonstrates how the bandwidth offered by millimeter wavelengths can be utilized to spread a low-data rate signal below the thermal floor of the environment. By using lowered transmit power combined with free space losses, the signal can be successfully received through a unique dispreading structure that does not rely on pre-detection for timing information. This data link ensures that it remains undetectable beyond a certain range from the transmitter while still providing reliable communication. A demonstration chipset of this concept was implemented in a 28 nm CMOS technology, and when paired with an InP receiver, it was able to decode signals up to 30 dB below the thermal noise floor. This was achieved by spreading a 9600 bps signal over 1 GHz of RF bandwidth from 93 to 94 GHz using a 64-bit spreading code. The transmitter for this chipset consumed 62 mW, while the receiver consumed 281 mW.

Another notable patent is the Microwave Reflector Link and CDMA-Spread Spectrum Reflector Apparatus. This system provides a method for communication between short-range wireless user devices, such as wearables, phones, or tablets, and a base station. Traditional low-power communication methods often involve inefficient amplification processes, requiring significant power from the user device. Tang's reflector link paradigm allows the user device to communicate by modulating the extent of the signal reflected back to the base station. An enhanced reflector is also introduced to mitigate the adverse effects of ambient reflections.
