Latest Patents

Allison's latest patents include innovative methods for transmitting metadata alongside data in COFDM broadcasting. One of his patents focuses on a transmitter apparatus that conveys metadata specifying the version of the COFDM broadcasting standard used. This metadata is transmitted through prescribed signature modulation of pilot carrier waves, which are interleaved with forward-error-correction coded digital signals. The receiver apparatus is designed to detect this metadata by searching for the signature modulation of the pilot carrier waves, enhancing the efficiency of data transmission.

Another significant patent by Allison involves a broadcasting system that utilizes digital television signals and metadata to modulate sets of OFDM carriers. This system is designed to improve the synchronization and transmission modes of digital television broadcasting. The mid-band carriers are capable of signaling new broadcast services, which is achieved through the modulation of these carriers with signature sequences composed of Zadoff-Chu sequences and pseudo-random sequences.
