Abstract: Aspects of a method and system for generation of signals up to extremely high frequencies using a delay circuit are provided. In this regard, a variable delay circuit may be adjusted such that an output signal generated by the delay circuit may be twice the frequency of a signal input to the delay circuit. The adjustment may be via an variable capacitance and/or a variable number of delay elements utilized to generate the output signal. Moreover, the adjustment may be based on a signal strength of the output signal. In this regard, the delay may be adjusted to maximize the signal strength of the output signal. The input signal may be delayed to generate a second signal that is 90° phase shifted relative to the input signal. The second signal and the input signal may be mixed to generate the output signal. The output signal may be filtered by a bandpass filter centered at twice the frequency of the input signal. Accordingly, the center frequency of the bandpass filter may be tunable.

Abstract: A system and method are used to provide uncorrelated code hopping in a communications system. A multi-bit linear shift register receives data and clocks the data fifteen times. A word assembler receives the shifted data and outputs a fifteen bit word. A mixer mixes the fifteen bit word with an numerical value of active codes to generate a mixed signal. A divider divides the mixed signal to produce a divided signal. A truncator truncates the divided signal to its seven most significant bits to produce a pseudo random hop number. A code matrix shifter circularly shifts the active codes in a code matrix based on the pseudo random hop number to produce a circularly shifted code. A transmitter transmits the circularly shifted code matrix.
