Abstract: A system and method for accelerating the reconfiguration of a field programmable radio frequency communication system having transmitter and receiver modes of operation, by outputting the data within the system at an accelerated rate (flush) when switching from a receive mode of operation to the transmit mode, or to another receive mode with another signaling scheme, and loading data to be transmitted into the system at an accelerated rate (queue) when switching into the transmit mode.

Abstract: A system and method for providing a configurable signal processing circuit for a field configurable radio frequency communication system that is adaptable to be configured to function with a variety of signaling schemes or waveforms, and including an intermediate frequency (IF) digital signal processing circuit. A “tool box” of configurable signal processing circuits is available for processing multi-bit digital signals into and out of the IF circuit. Control registers receive digital instructions to select, interconnect and configure various circuits from the tool box to provide added signal processing for the selected the transmitter or receiver mode of operation as a function of the selected signaling scheme.

Abstract: A digital signal processing circuit for field programmable radio frequency communications system including a digital controlled numerical controlled oscillator (NCO), dual digital signal conditioning circuits, and dual mixer circuits. The various circuits are responsive to digital commands for configuring the digital signal processing circuit to function with a variety of signaling schemes or waveforms. When configuring for angle modulation, a single conditioning and mixer is used and the modulating digital input signal is up converted to the center frequency of the NCO by the conditioning circuit and applied to an offset input of the NCO.

Abstract: A system and method for controlling the output of multi bit digital signals from a field configurable radio frequency communications system having a first register adapted to receive multi bit digital signals from a variety of sources, wherein the register includes a tag section for providing tag bits to the signal bit to identify the source of the signal. A second register is provided for using the tag bits for storing the multi bit signals according to the source of the signal. The multi bit signals and tag bits can be outputted directly from the first register, or from the second register, depending on the mode of operation selected by the output signal receiving circuit.

Abstract: A digital noise reduction for a radio frequency receiver communication systems that is field programmable to function with a large variety of signaling schemes or waveforms. The noise reduction arrangement includes circuits to convert the mulit bit digital signal (including noise impulses therein) into logarithmic form and uses exponential averaging to determine the presence of noise and the magnitude thereof. Various threshold circuits, the exponential averaging circuits and an exponential decay circuit are responsive to digital commands to set the thresholds for noise detection and control when the noise should be blanked and the duration of blanking.
