摘要： An ultrasonic scanner imaging system includes connections to one or more transducer arrays of at least M elements each, a transmit beamformer with N processors, and a receive beamformer with N processors. Separate transmit and receive multiplexers permit switching between transmit firings to any contiguous N-element transmit or receive aperture completely within a transducer array or straddled across two arrays. The transmit and receive apertures for a given firing may be independently placed and are not required to coincide. Such flexibility supports random aperture placement, sliding aperture acquisitions, and synthetic aperture acquisitions. The multiplexers also permit shorting adjacent transducer elements to enable 2N elements to be used in conjunction with N-channel transmit/receive beamformers. Beamforming to create synthetic apertures of P*N

摘要： A heterodyne communication system uses coherent data modulation that is resistant to phase noise. In particular, a pilot tone and reference clock signal are transmitted along with the modulated data to form the basis of an electrical demodulation local oscillator at the receiver. The pilot tone and/or reference clock signal carry phase noise which is correlated with the phase noise in the data signal. At the receiver, the local oscillator is generated from the pilot tone and reference clock signal in a manner so that the local oscillator also has phase noise which is correlated with the phase noise in the data signal. Thus, the two noise components can be used to cancel each other during demodulation of the data signal using the local oscillator.

摘要： A frequency division multiplexing (FDM) node used in optical communications networks provides add-drop multiplexing (ADM) functionality between optical high-speed channels and electrical low-speed channels. The FDM node includes a high-speed system and an ADM crosspoint. The high-speed system converts between an optical high-speed channel and its constituent electrical low-speed channels through the use of frequency division multiplexing and preferably also QAM modulation. The ADM crosspoint couples incoming low-speed channels to outgoing low-speed channels, thus implementing the ADM functionality for the FDM node.

摘要： Attenuation caused by dispersion in an optical fiber communications system is compensated. A number of low-speed channels is to be transmitted across an optical fiber. Each low-speed channel is allocated a different frequency band for transmission. The attenuation caused by dispersion is estimated for each of the frequency bands. The power of each low-speed channel is adjusted to compensate for the estimated attenuation. The power-adjusted low-speed channels are frequency division multiplexed together to produce an electrical high-speed channel suitable for transmission across the communications system.
