摘要： An optical system may include optical transmitters to provide respective optical signals. Each of the respective optical signals may provide one or more carriers in an optical channel. The optical channel may include multiple carriers associated with the respective optical signals. First and second carriers, of the multiple carriers, may have a particular carrier space width. The particular carrier space width may include a frequency error associated with one or more optical signals of the respective optical signals. The optical system may include a control system to determine the frequency error and cause one or more of the optical transmitters to adjust the particular carrier space width based on the adjusted frequency error.

摘要： A system, method, and apparatus is disclosed for interpolation of an output of an analog to digital converter (ADC) to enable operation of the ADC at a sampling rate that is independent of the sampling rate for a DSP core so as to efficiently enable operation at higher date rates. According to one of the embodiments, an interpolation circuit is coupled between the ADC and DSP core and receives a first plurality of samples of data at the first data rate from the ADC and supplies a plurality of samples of second data at a second data rate to the DSP core; the second data rate being less than the first data rate. According to one of the embodiments, the interpolation circuit includes a memory and a FIR filter circuit having filter tap coefficient values selected to provide attenuation at high frequencies to reduce aliasing noise.

摘要： A system, method, and apparatus is disclosed for enabling a constant modulus algorithm (CMA) to be reliably used for blind equalization training of an equalizer. According to one embodiment, received signals in a binary phase shift keying (BPSK) format are converted to a quadrature phase shift keying (QPSK) format, to which CMA processing can be reliably applied for equalization. According to another aspect of this embodiment, the equalized QPSK signals are rotated to convert the signals to an equalized BPSK format for output.

摘要： A circuit (2) and method employing logic circuitry (30) and memory (40) identifies a reverse link limited channel (80). The logic circuitry (30) identifies a reverse link limited channel based on determining that an access probe failure occurred on a channel (64). The logic circuitry (30) causes the memory to store reverse link limited channel data (80) in response to the logic circuitry (30) determining that the access probe failure occurred. The reverse link limited channel data (80), for example, may be a channel identification associated with the channel (64), a base station identification associated with the channel (64), a location identification of the circuit (2) or any data suitable for identifying and adapting dynamically to the reverse link limited channel.

摘要： This invention relates to a method and apparatus for measuring the phase change of an output optical signal from a device. In one embodiment an input optical signal is split into first and second optical signals, and the first optical signal is passed through the device while applying an external stimulus to the device, to produce an output optical signal having a phase shift. The carrier frequency of the second optical signal is changed, and the output optical signal and the changed second optical signal are then combined. The combined signal is detected in accordance with the external stimulus applied to the device, and the phase change of the output signal of the device is measured as a function of the external stimulus applied to the device.

摘要： A method and apparatus is provided for simultaneously accessing a broadcast channel which allows for maintaining registration on the broadcast channel and a second channel. The broadcast channel includes a reverse link access channel for a portable communication device (120) to send registration messages to a base station and the method initially includes the step of determining whether a predetermined event requiring registration of the portable communication device on the broadcast channel has been detected (302, 304, 306). After detecting the predetermined event, it is determined whether the portable communication device is communicating on the second channel (308). If not communicating on the second channel (308), registration on the broadcast channel is accomplished by transmitting a registration message on the reverse link access channel (320). If communicating on the second channel (308), the registration message is transmitted on the broadcast channel asynchronously (340) or, if supported by the base station (110), as a databurst of a packet of information on the second channel (330).
