His innovative approach has garnered attention in both academic and industrial circles.

Latest Patents

Wang holds a patent for a "Cross-product detection method for a narrowband signal under a wide range of carrier frequency offset (CFO) using multiple frequency bins." This patent describes a synchronizer that generates cross-products of In-phase (I) and Quadrature (Q) samples, storing the sign bits for the sine and cosine cross-products. The method involves comparing these sign bits to a local reference of a frame-start bit-sequence, accumulating the results as I and Q correlations for symbol and half-symbol sampling. The linear combinations of these correlations generate results for frequency bins that peak at different implied CFO settings. This innovative method reduces computational complexity by retaining only the sign bit of each cross-product for correlation, allowing for support across a wide CFO range.
