Abstract: A spread spectrum communication system includes a transceiver configured to transmit a spread spectrum waveform. The spread spectrum waveform comprises transmitted signals at varying frequencies within a radio frequency spectrum of operation. The frequency variation is controlled according to a hopping sequence. A spectral sensor of the communication system is configured to dynamically scan the radio frequency spectrum of operation and to generate channel occupancy data based upon the scans. A real time hopping sequence generator is configured to dynamically generate the hopping sequence in real time as a function of the channel occupancy data.

Abstract: A method and apparatus for signal acquisition with transmit blanking compensation compensates for collisions between a desired received signal and a transmitted signal. A blanking block blanks a received signal when the transmitted signal is transmitted and stops blanking when the transmitted signal stops to provide a received signal with blanking. A correlation block correlates the received signal with blanking with a known sequence of symbols corresponding to the desired received signal and outputs a correlation metric and a number of symbols blanked. Means for adjusting the correlation metric or a variable threshold using the number of symbols blanked are provided. A decision block compares the adjusted correlation metric to a fixed threshold or the correlation metric to the variable threshold. If the adjusted correlation metric exceeds the threshold or if the correlation metric exceeds the variable threshold, the decision block determines that the desired signal is detected.

Abstract: An arbitration unit according to an embodiment of the present invention is disclosed. The arbitration unit includes an allocation unit that assigns a first number of slots in a frame to a first flow and a second number of slots in the frame to a second flow. The arbitration unit includes a scheduling unit that assigns first slot positions to the first number of slots in the frame and second slot positions to the second number of slots in the frame using a binary distribution tree.

Abstract: In allocating bandwidth to data for transfer through a network device, bandwidth is allocated to committed data traffic based on a guaranteed data transfer rate and a queue size of the network device, and bandwidth is allocated to uncommitted data traffic using a weighted maximum/minimum process. The weighted maximum/minimum process allocates bandwidth to the uncommitted data traffic in proportion to a weight associated with the uncommitted data traffic.
