Latest Patents

Hwang's latest patents include a PBCH signal accumulation method and a PBCH decoder designed to enhance the performance of 5G NR receivers. This invention relates to a method of accumulating and decoding a PBCH signal received by a 5G NR receiver. The method involves generating an inversion vector to negate at least one bit of a system frame number included in the received PBCH signal. It also includes performing accumulation over at least one frame by executing modulo addition on the generated inversion vector and the received PBCH signal, followed by decoding the accumulated PBCH signals and checking the validity of the decoded PBCH to reconstruct the system frame number.

Another notable patent is the channel state information extraction method and MIMO receiver using QR decomposition and MMIB metric. This invention pertains to a CSI extraction method in a MIMO receiver used in wireless communication systems. The method includes obtaining an effective channel matrix through matrix multiplication of a precoding matrix and a channel estimation value obtained via a CSI-RS. It calculates the upper and lower bounds of a minimum distance for each layer through QR decomposition for the effective channel matrix. The method maps these bounds to each codeword and extracts a mean mutual information per bit (MMIB) metric, which represents the transmission capacity per unit frequency for each codeword.
