Latest Patents

Rex A Hand holds a patent for a seamless frequency hopping system. This system utilizes a programmable digital signal processor along with interface circuitry in conjunction with a frequency hopping radio. The invention incorporates concepts such as audio time compression, hop by hop automatic gain control, and time repeating squelch to enhance the sound quality of frequency hopped analog communication. The process begins with incoming uncompressed audio being sliced into time segments that correspond to each frequency hop. The audio is then compressed to a certain percentage of its original length, with a dead time and pilot signal added to the front. The processed audio signal is subsequently sent to the radio for modulation and broadcasting. A second radio receives the signal and demodulates it back into an audio format.
