Latest Patents

One of Jungnam Yun's latest patents is an "Apparatus for estimating and compensating carrier frequency offset and data receiving method in receiver of wireless communication system." This invention relates to a method for estimating and compensating a carrier frequency offset, which is crucial for maintaining the integrity of data received in wireless communication. The apparatus correlates a received signal with a delayed version of itself within a correlation window, which is determined based on a Cycle Prefix (CP) and a preamble repetition length. This innovative approach allows for the compensation of phase discrepancies and the estimation of initial carrier frequency offset values.

Another notable patent is the "Method of detecting a frame boundary of a received signal in digital communication system and apparatus of enabling the method." This method involves generating a delayed signal from the received signal and calculating a correlation value to determine the frame boundary index. By performing correlation calculations without oversampling, the accuracy of frame boundary detection is enhanced while reducing the complexity of both hardware and software.
