Dr. Hyuck Kwon is a professor at Wichita State University with an exceedingly accomplished background in communication systems. His patented technologies improve frequency hopping capabilities, increase data speeds, optimize antenna efficiency, as well as minimize and track error rates. Global connectivity increases the value of these technologies.
Communication is headed towards being totally wireless, and with this shift comes the increasing need for reliable reception and secure communication. Cell phones are the most prevalent form of communication systems found throughout the world today, and are now the main mode of communication and access to the internet.
In accordance to the CDC’s biannual National Health Interview Survey. Less than 5% of households in the United States depended on cell phones instead of landlines in 2003; but by 2016, that number exploded to more than 50%. In the United States alone, wireless telecommunication carriers (such as Verizon, AT&T, Deutsche Telekom AG, and Sprint) collectively bring in $254.5 billion in revenue, and this industry is expected growth at an astonishing 9.5% per year over the next five years. Cell phones now claim responsibility for a considerable amount of internet usage, with the average smartphone generating 450 MB of mobile traffic per month. In 2012, there were 6.3 billion mobile
network subscriptions worldwide, with this number climbing approximately 9% per year.
Electronic warfare has permanently changed the scope of a battlefield. The Department of Defense is seeking technology that allows Special Operations Forces with the ability to operate effectively in denied airspace. This need includes anti-jam GPS and electronic warfare systems. The C4I Community of Inter(Command, Control, Communications, Computers and Intelligence) supports successful mission execution at all echelons, regardless of network/system status. For these reasons the Department of Defense is looking for improved technology to increase the military's combat capabilities. Non-cyclical frequency hopping patterns, increased antenna efficiency, information encryption, and recording error rates in data transmission are all important areas of electronic warfare.
Adaptive Frequency Hopping
Patent No. US9819387 B2
Heightens Signal Clarity and Security
Radio communication systems employ frequency hopping techniques to avoid jamming and detection. This means the frequency of the transmitted signal is systematically changed within the range of the receiving device. Current frequency hopping methods are not adaptable - leaving them more susceptible to jamming or detection. Dr. Kwon invented a frequency hopping algorithm that takes into account the probability of a given frequency being jammed, increasing signal clarity and security. Based on the probability of a frequency experiencing jamming, the algorithm generates an adaptive frequency hopping pattern with safer frequencies. This yields a clearer and more secure signal.
Exact Symbol Error Rate Generation
Patent No. US9742460 B2
Discovers Optimal Modulation Pattern for Frequency Hopped Signals
Coherent frequency hopping patterns, where the receiver and transmitter have synchronized clocks, are used with slow frequency hopping spread spectrum systems for a new protected tactical waveform standard. This presented technology is a system and method for transmitting data and recording the symbol error rate of the communication. The radio signal can then be modulated with respect to the recorded symbol error rate information, optimizing the modulation pattern and decreasing error probability.
Hexaferrite MIMO Antenna
Patent No. US9711869 B1
Increases Data Speed and Minimizes Error
Multiple-input-multiple-output (MIMO) communication systems present wireless technologies with higher data transmission rates. However, MIMO systems require extra space between reception antennas, limiting the feasibility of using multiple-input-multiple-output. The presented technology solves this issue. A new MIMO antenna design utilizes hexaferrite materials and optimal geometric construction to preserve a clear signal with reduced size and spacing, while still benefiting from the increased capabilities of MIMO technology.
Spreading Sequence Design for Relay Networks
Patent No. pending - Allowed 1/4/18
Encrypts Data with Fake Signals
One technique for communication security is to generate patterns of noise which disguises the signal from interceptors, but can still be decrypted at the receiver unit. This technology presents a fully connected uplink and downlink relay network system that uses pseudonoise spreading and despreading sequences, which maximizes the signal-to-noise ratio. The network systems comprises one or more transmitting units, relays, and receiving units. The computer encodes and decodes communication signals with respect to the optimum pseudonoise spreading sequences. The optimized pseudonoise sequence cancels out the majority of interference, resulting in the clearest signal possible.
