摘要： A system (100) comprising: a first unit (104) and one or more second units (104). The first unit (102) comprises: a timing reference (114) configured to provide a master-timing-reference-signal; a master time block configured to provide a master-time-signal (117) for the first unit (102) based on the master-timing-reference-signal; and a first interface (122) configured to: receive timestamped-processed-second-RF-signals from the one or more second units (104); and provide a first-unit-timing-signal (262) to the one or more second units (104) based on the master-time-signal. The one or more second units (104) each comprise: a slave time block (141) configured to: determine a slave-time-signal (142) for the second unit (104) based on the master-timing-reference-signal; determine one or more second-timing-values based on the slave-time-signal; determine an adjustment-time based on the first-unit-timing-signal received from the first unit (102) and the second-timing-values; and adjust the slave-time-signal based on the adjustment-time.

摘要： A receiver controller configured to control a receiver in receipt a signal comprising a series of time-consecutive symbols is disclosed. Each symbol includes an FFT window and a guard interval and the guard interval includes a cyclic prefix or postfix. The receiver controller is configured to control the receiver to acquire at least one signal parameter. The receiver controller is also configured to, based on a plurality of samples of the received signal, each sample having a predetermined sample length, determination of a plurality of correlation values based on pairs of the plurality of samples, said pairs of samples separated in time by a predetermined separation number of samples.

摘要： A system includes a first integrated circuit device, a second integrated circuit device, and a reference clock provided to the first and second integrated circuit devices. The first integrated circuit device detects a first edge of a first clock utilized by the first integrated circuit device, detects a second edge of the first clock, determines a first count of cycles of the reference clock between the first edge and the second edge, and communicates the first count to the second integrated circuit device. The second integrated circuit device receives the first count, provides a third edge of a second clock utilized by the second integrated circuit device, determines that a first number of cycles of the reference clock since providing the third edge is equal to the first count, and provides a fourth edge of the second clock in response to determining that the first number of cycles is equal to the first count.

摘要： Aspects of the disclosure are directed to processing signals including data exhibiting characteristics that facilitate assessment of transmission errors. As may be implemented in accordance with one or more embodiments, parameters are generated based signal transmission characteristics and are indicative of a different types of signal characteristics, including an amount of error correction that has been carried out on the signal. Two or more of the parameters are selected based on properties of signal disturbance under different reception conditions for the signal, and a degree of disturbance in the signal is predicted based on the selected parameters and signal conditions for the respective parameters at which the signal cannot be corrected. An output generated with the signal is then controlled, based on the predicted degree of disturbance and a threshold degree of disturbance.

摘要： An apparatus and method are provided. A first buffer is configured to store a first packet stream, the first buffer comprising a first read pointer pointing to a first position in the first packet stream. A second buffer is configured to store a second packet stream. The second packet stream corresponds to the first packet stream and the second buffer comprises a second read pointer. A controller is configured to determine a second position in the second packet stream that corresponds to the first position in the first packet stream and adjust the second read pointer to point to the second position.
