Latest Patents

Liu’s latest listed patent, “Compress-forward coding with N-PSK modulation for the half-duplex Gaussian relay channel,” describes systems and methods for transmitting information through a relay channel. The approach uses compress-forward coding and applies Wyner–Ziv coding at the relay to take advantage of the statistical relationship between signals received by the relay and destination.

The patent also discusses quantizer design and channel-code selection. It describes using low-density parity-check (LDPC) codes to protect source data, alongside nested scalar quantization and irregular repeat-accumulate codes for Wyner–Ziv coding at the relay. At the destination, information is decoded from a source transmission received during a first interval and a combined source-and-relay signal received during a second interval.
