摘要： A method and system eliminate spectral lines and shapes the power spectral density of an ultra bandwidth signal. First, a train of non-periodic pulses is generated. The non-periodic pulses are then modulated in time according to uncorrelated symbols. A polarity of the non-periodic pulses is inverted randomly before transmitting the non-periodic pulses as an ultra wide bandwidth signal to eliminate spectral lines and to shape a power spectral density of the ultra wide bandwidth signal.

摘要： A method eliminates spectral lines in a time hopping ultra wide bandwidth signal. First, a train of pulses is generated from input symbols. The pulses are then modulated in time according to symbols. The modulation can use pulse position modulation and time hopping. A polarity of the pulses is inverted randomly before transmitting the pulses as an ultra wide bandwidth signal. By randomly inverting the polarity of the pulses spectral lines in the ultra wide bandwidth signal are eliminated.

摘要： An OFDM receiver detects FSK symbols in a communications network. An FFT has an input connected to receive temporal samples of a received, frequency-hopped FSK signal. Outputs of the FFT represent the FSK signal in a frequency domain. The outputs are grouped according to predetermined frequencies assigned by a transmitter of the FSK signal. An energy for each group of outputs is determined, and the energies of each group are then compared to recover a data stream from the FSK signal.

摘要： Methods and systems for detecting and synchronizing to frequency hopped packets are presented. A technique for detecting a transmitter frequency hopping pattern includes receiving a packet of preamble symbols respectively transmitted over multiple frequency sub-bands according to the transmitter frequency hopping pattern, and partitioning predetermined frequency hopping patterns into disjoint groups of patterns, each group of patterns having an associated periodicity of the received preamble symbols. A group of patterns is selected by comparing a correlation metric of two received preamble symbols for each of the associated periodicities in a first selected frequency sub-band, and a pattern from the selected group of patterns is selected based on a timing of a detected first peak of the correlation metric in a second selected frequency sub-band. Optionally, the selected pattern is verified by comparing the correlation metric at a particular time interval to a threshold value in a third selected frequency sub-band.

摘要： A method and system communicates ultra wide bandwidth signals using orthogonal frequency division multiplexing modulation. QPSK input symbols are frequency interleaved. The frequency interleaved symbols are spread over a plurality of tones, and the tones are modulated for transmission over an ultra wide bandwidth channel. When the tones are received, the received tones can be de-spreaded to recover the input symbols.
