Title: Zheng Zi Li: Innovator in Wireless Communication Technologies
Introduction
Zheng Zi Li is a prominent inventor based in Seongnam-si, South Korea, known for his groundbreaking contributions to wireless communication technologies. With a portfolio of five patents, his work has significantly advanced the field, particularly in the development of decoding apparatuses and channel estimation methods.
Latest Patents
Zheng's latest patents include a decoding apparatus and method designed for systems supporting Orthogonal Frequency Division Multiple Access (OFDMA) schemes. This innovative apparatus compensates received signals based on a wireless channel estimation result, allowing for simplified decoding through a coherent method. The decoding method involves several steps: receiving a Quadrature Phase Shift Keying (QPSK) modulated signal, applying channel estimation to compensate received signals, performing subcarrier demodulation to generate correlation metrics, and finally, decoding using a derived decoding metric. This approach enhances efficiency by allowing the apparatus to adapt to wireless channel conditions effectively.
Another significant patent from Zheng is focused on estimating the channel in OFDM/OFDMA-based wireless communication systems. This method involves generating two pilot signals for each antenna and transmitting them over Orthogonal Frequency Division Multiplexing (OFDM) symbols. The signal generation incorporates weight values that vary based on symbol indexes, ensuring improved transmission quality and reliability.
