Latest Patents
One of Park's latest patents is a method and apparatus for constant envelope quadrature amplitude modulation. This system aims to solve the bandwidth efficiency problem caused by limited frequency resources. It implements a constant envelope characteristic for a non-linear communication system based on a 16-QAM (Quadrature Amplitude Modulation) system. The system restricts the data to 3-bit and adds a parity bit to ensure a constant envelope within the 16-QAM framework. This allows for efficient modulation of data transmitted in 4-bit units.
Another significant patent is the constant envelope quadrature-quadrature amplitude modulation system. This innovation limits the transmitted data to 4-bit and adds 4-bit parity to maintain a constant envelope in the Q²AM system. The system modulates 8-bit data in 2-bit units and includes a constant envelope encoder, multiple mappers, and mixers to generate the necessary signals for transmission.
