Title: Innovations of Houman Rastegarfar
Introduction
Houman Rastegarfar is an accomplished inventor based in Tucson, AZ. He has made significant contributions to the field of communications technology, holding 2 patents that showcase his innovative approach to solving complex problems in mobile fronthaul networks and optical transmission systems.
Latest Patents
One of his latest patents is titled "Probabilistically coded modulation for fronthaul networks." This invention involves a controller that facilitates communication between a baseband unit (BBU) and a remote radio head (RRH) in a mobile fronthaul (MFH) network. The controller initializes a pseudorandom seeding in both the BBU and RRH, enabling them to generate matching pseudorandom bit sequences (PRBS) for synchronized communication. It also selects a wavelength and route for communication, chooses an error correction code and modulation format, encodes physical layer parameters into the PRBS, and monitors the data stream for bit error rate changes.
Another notable patent is "Proactive channel probing for wavelength switching in optical transmission systems." This invention provides a proactive and non-obtrusive channel probing scheme that accurately predicts channel power, gain, and optical signal to noise ratio (OSNR) without disrupting existing connections. For instance, using a probe signal with a 5 µs pulse duration in a single-hop network, rapid wavelength switching is achieved with power excursions of less than or equal to 0.2 dB for various loading configurations.
