Latest Patents

One of Jianxuan Du's latest patents is titled "Training frames for MIMO stations." This invention describes a method for transmitting training frames in a MIMO system. A long sequence of training frames is sent from station B to station A through the MIMO channel, where station A consists of N antennas and N RF chains, while station B also includes N antennas and N RF chains. The number of frames in the long sequence is at least equal to a specified lower bound operator. In response to receiving the long sequence, a short sequence of training frames is transmitted from station A back to station B.

Another significant patent is "Minimizing feedback rate for channel state information in MIMO systems." This method aims to minimize the feedback rate for channel state information from a receiver to a transmitter in MIMO communication systems. The process involves determining a temporal autocorrelation function of the channel between the transmitter and receiver, estimating the spatial covariance information of the channel, and then calculating the minimum feedback rate based on actual channel state information along with the estimated spatial covariance and temporal autocorrelation function.
