Latest Patents

One of his latest patents is titled "Apparatus for generating 2D spreading code and method for the same." This invention proposes an apparatus that includes a column counter, a row counter, a codeword selector, and a logic unit. The logic unit performs operations on the outputs of the column and row counters, as well as the codeword selector, to generate a 2D spreading code of the desired order. This technology is particularly advantageous in OFDM systems, as it increases the number of subscribers while reducing interference.

Another notable patent is the "Apparatus of transmitter and receiver for MIMO MC-CDMA system." This invention utilizes modified orthogonal transmit diversity (MOTD) encoders at the transmitter to enhance space and time transmission diversity. The system includes a P-way combiner that connects the MOTD encoders to multi-carrier modulators, each linked to a set of antennas. At the receiver end, multi-carrier demodulators are equipped with amplitude/phase compensators to address distortion, allowing for the exploration of space, time, and frequency diversity.
