Title: Mojtaba Shariat: Innovator in Communication Systems
Introduction
Mojtaba Shariat is a notable inventor based in Matawan, NJ (US), recognized for his contributions to communication systems. He holds 8 patents that showcase his innovative approaches to enhancing digital broadcasting and communication technologies.
Latest Patents
One of his latest patents is a method and apparatus for establishing interleaver synchronization in an orthogonal frequency division multiplexing (OFDM) communication system. This invention discloses interleaving methods and apparatus for an in-band on-channel digital audio broadcasting system. The guard periods that separate adjacent symbols in a conventional OFDM system provide a mechanism for OFDM frame synchronization. By utilizing the guard period of successive OFDM frames, unique patterns are established to facilitate interleaver synchronization. The invention identifies the beginning of each interleaver block by positioning the fourth negative cyclic prefix with OFDM frame zero. Additionally, it can identify the midpoint of each interleaver block using a unique cyclic prefix pattern. A receiver monitors the incoming data stream for a synchronization pattern to establish interleaver synchronization, detect when synchronization is lost, and correct false synchronization. Another significant patent is a frame formatting technique that fills a fixed-length master frame with variable-length frames while adding additional data to synchronize these frames. This technique maximizes the randomness of the fixed-length master frame, enhancing the efficiency of digital broadcasting systems.
