Latest Patents

Xiaodan Gan holds a patent for a method aimed at reducing channel estimation error in an OFDM system. This method involves channel response estimation based on specific training symbols, including a virtual training symbol. The process begins with the reception of at least one preamble symbol from a transmitted data frame. A first channel state information is estimated from this preamble symbol. Subsequently, at least one signaling symbol is received and equalized, from which a rate factor and a length factor are extracted. A virtual training symbol is then formed using these factors. Finally, a second channel state information is estimated, allowing for the equalization of data symbols through channel correction.
