Latest Patents

Lee's latest patents include a "Wireless positioning server using clock offset calibration positioning method using the same" and a "Sequential transmission multi-beamforming method with low complexity using Hadamard matrix." The wireless positioning server utilizes clock offset compensation to accurately estimate the position of a tag that requires position information. By predicting the distance between a beacon and the tag, the server minimizes errors caused by clock offsets. This is achieved by measuring the relative clock frequency ratio between beacons and compensating for their clock frequencies during distance estimation. The multi-beamforming method, on the other hand, employs a Hadamard matrix to create a simple codebook, reducing the number of weighted vectors and hardware complexity while maximizing diversity gain.
