Latest Patents
Samuel Lim holds a patent for an "Unequal hierarchical communications modulation method." This method utilizes a 16-ary quadrature amplitude modulation (QAM) modulator combined with a convolutional encoder. It effectively provides unequal protection to two different segments of streaming input data. The approach improves power efficiency while maintaining the same bandwidth efficiency. The first segment is encoded as coded data in the least significant bits (LSBs), while the second segment remains uncoded in the most significant bits (MSBs). This unique configuration allows for reliable interquadrant demodulation and detection, with the LSBs benefiting from convolutional encoding and decoding for high reliability detection.
