Abstract: A technique for time domain avoidance of communications link interference sources characterized by intermittent, periodic short bursts of energy. A transmitting source can be assigned two time slots within a time domain multiple access data frame over which each data packet can be transmitted. The time slots are separated by a duration greater than that of an interference burst, such that an interference burst does not affect both time slots in any given frame. Therefore, the data packet can be received on at least one of the two assigned time slots. Transmitter power consumption can be reduced by calculating the timing of the periodic interference bursts, and only transmitting a data packet on one of the two assigned time slots that will not coincide with an interference burst in each frame. Communications link capacity can be improved during the presence of interference by synchronizing the data frame to the timing of the interference bursts.

Abstract: A method for transmitting a spreading data signal and an intelligence signal to allow a passive recovery. Before transmission, the spreading data signal and the intelligence signal are filtered by a high-pass filter and a low-pass filter, respectively. The filtered spreading data signal and the intelligence signal are then summed to compose a composite intelligence/spreading signal (CISS). Due to the high-pass and low-pass filtering, the spreading data signal and the intelligence signal of the CISS are separated in the frequency domain. Next, the CISS is modulated by a RF modulator before transmitting to a remote receiver. As the spreading data signal and the intelligence signal of the CISS are separated in the frequency domain, the remote receiver can easily recover the intelligence signal from the received modulated CISS without complicated conversion devices.

Abstract: The present disclosure discloses a method and apparatus for slicing data, or “squaring up” a signal such as the output of a wireless receiver demodulator for proper interface with conventional digital logic circuits. The method involves the receiving of an input signal, the generation of a reference level, the comparison of the input signal to the reference level, and the measurement and storage of the reference level. The reference level is generated by applying the input signal to a filter, which has been previously set to an initial condition. The reference level is measured at a predetermined point in a receive data frame, and is maintained at the desired level throughout the remainder of the frame. After a frame has been received, the reference level is stored if the frame data output from the data slicer contained no errors.
