摘要： The present invention relates generally to communication systems, both wired and wireless, employing a continuous phase modulation (“CPM”) waveform with a minimum shift keying (“MSK”) preamble. The present inventive system and method uses information from contiguous Fourier Transforms taken on contiguous data blocks to determine baud rate, phase, frequency offset, and bit timing of the CPM waveform or can be used to determine the frequency of continuous wave waveform. More particularly, the inventive system and method is applicable to the military satellite communications UHF frequency band for deciding whether a signal of interest is.

摘要： A time division multiple access (TDMA) waveform for controlling a MIL-STD-188-183 compliant demand assignment multiple access (DAMA) satellite communication network contains a short duration and minimal data content, time-hack, that is repeatedly transmitted by a supervisory control radio, so that the time hack occurs twice within a DAMA frame, ensuring that every radio can acquire frame synchronization, irrespective of overlap in receipt of one of the time-hacks with a voice/data channel transmission by that radio. The time-hack also identifies which one among a list of different frame formats stored in the radio is to be employed.

摘要： A system and method for compensating for angular distortion of a received waveform is disclosed. One embodiment measures the angular position of a current symbol, the preceding symbol and the succeeding symbol, calculates the phase shift between the current symbol and a preceding symbol and the phase shift between the current symbol and a succeeding symbol, uses the phase shifts to enter a 2-D lookup table to extract a phase correction factor, then uses the phase correction factor to modify the angular position of the current symbol.

摘要： A wireless communication system may include a wireless transmitter configured to transmit a message including data symbols arranged to include an attention packet and sequencing packets thereafter. The sequencing packets may include common value first portions with each data symbol having a same value, and marker second portions having a marker data symbol. The wireless communication system may include a wireless receiver configured to receive the message from the wireless transmitter based upon the attention packet and the sequencing packets by determining a time delay based upon the positions of the marker data symbol, and reordering data symbols of the message based upon the determined time delay.

摘要： A communications system includes a target receiver having a passband and configured to receive an intended signal within the passband. The communications system also includes a jammer configured to jam the target receiver from receiving the intended signal. The jammer has at least one antenna, a jammer receiver coupled to the at least one antenna, a jammer transmitter coupled to the at least one antenna, and a controller configured to cooperate with the jammer receiver. The controller is configured to detect the intended signal and to generate an interfering signal comprising a continuous phase modulation (CPM) waveform having a constant envelope so that the interfering signal at least partially overlaps the passband of the target receiver.

摘要： A PDC-equipped rotary drag bit especially suitable for directional drilling. Cutter chamfer size and backrake angle, as well as cutter backrake, may be varied along the bit profile between the center of the bit and the gage to provide a less aggressive center and more aggressive outer region on the bit face to enhance stability while maintaining side cutting capability, as well as providing a high rate of penetration under relatively high weight on bit.

摘要： A drill bit and method of drilling a subterranean formation are disclosed in which the drill bit is configured with a non-axial gage portion of a bit body. The non-axial gage portion of the bit body presents a peripheral profile which is not parallel to the centerline of the bit body to provide a contact area for engagement of the sidewall of the borehole by at least one cutting element carried by the non-axial gage portion to enlarge the borehole from a first diameter cut by cutting elements on the bit face. The configuration of the drill bit lessens loading on the cutting elements of the drill bit, facilitates maneuverability of the drill bit downhole and enhances steerability of the drill bit.
