Introduction
Pan Zhengang is a notable inventor based in Hong Kong, China. He has made significant contributions to the field of power line communication and Orthogonal Frequency Division Multiplexing (OFDM). With a total of 4 patents to his name, his work has advanced the technology used in data transmission over power lines.
Latest Patents
One of Pan Zhengang's latest patents is focused on an OFDM symbol structure for power line communication. This method involves packing data into a symbol body, adding a first pad in front of the symbol body to create a full symbol, and determining the time instance when the peak absolute voltage point of the AC electric power occurs. The full symbol is then sent through the power line in synchronization with this time instance. Additionally, based on interference condition detection, the invention allows for adaptation on the receiver side. Another significant patent involves channel estimation techniques for OFDM. This invention includes a channel estimator that receives a signal comprising multiple symbols, each containing pilots and data subcarriers. The estimator utilizes a first channel response estimate from a pilot subcarrier in the first symbol to select a weight matrix from pre-generated options, generating channel estimation information for data subcarriers.
