Latest Patents

One of his key patents is titled "Physical layer secure communication against an eavesdropper with arbitrary number of eavesdropping antennas." This patent outlines a method for secure transmission that includes several steps. First, communication between the legitimate transmitter, Alice, and the legitimate receiver, Bob, is confirmed. Alice then randomly generates a key bit and maps it into a key symbol, performing an XOR operation with the confidential information to create encrypted bits. Bob transmits a pilot sequence to Alice, who calculates a candidate precoding space and transmits modulated symbol streams. Bob measures the received signal strength, estimates the corresponding antenna vector, and demodulates the received symbol streams to obtain the confidential information.
