Latest Patents

One of his latest patents is a "Smart antenna beamforming device in communication system and method thereof." This device includes a Direction Of Arrival (DOA) estimation unit that estimates DOAs of received signals based on a data subcarrier matrix. It also features a pre-spatial filtering unit that utilizes the estimated DOA to perform filtering operations, generating filtering matrices. Additionally, a signal identification unit identifies original and interference signals, while a spatial filtering unit generates an interference-plus-noise covariance matrix to eliminate interference signals. Finally, a channel estimating and signal combining unit performs a maximal ratio combining operation to produce a combined final beam.

Another significant patent is the "Hardware-efficient demodulator for CDMA adaptive antenna array systems." This demodulator operates within a mobile radio communication system, where a correlators bank computes correlation values with a local code sequence. A beamformer calculates beamforming weight vectors, while a searchers bank provides reliable timing information for multipath searches. The system includes a multipath combiner that outputs signals based on time alignment.
