摘要： All digital reference frequency locking. An all digital approach is provided for operation within one or more CMs within a cable modem communication system to lock the upstream of the one or more CMs to the downstream symbol clock provided from a CMTS. The locking of the CM's upstream may be performed using one of at least three different functions: (1) Locking the upstream symbol clock phase to the downstream symbol clock phase, (2) Locking the downstream symbol clock phase to the headend reference clock phase (typically 10.24 MHz or integer multiple thereof), and (3) Locking the upstream carrier frequency to the downstream symbol clock frequency. The all-digital techniques for supporting all digital reference frequency locking functionality provide high performance to support S-CDMA and other synchronous modulation techniques.

摘要： Disclosed are a method, system and/or device of continuous barcode tape based inventory location tracking. In one aspect, a method includes analyzing a layout diagram of a distribution center. The method further includes determining that the layout diagram includes a shelf. A number of segments associated with the shelf based on a forecasted allocation of an inventory on the shelf are calculated. A bar code tape having a globally unique identifier (GUID) associated with each segment of the number of shelves is automatically generated using a processor and a memory of a central inventory tracking system.

摘要： An inexpensive synchronous detection module is disclosed for a sideband signal receiver that provides for flexibility in design of the tuner. The detection module is adaptable to detection of upper or lower sideband signals. One embodiment includes an analog-to-digital converter, a Hilbert transform filter, a sideband selection switch, a complex multiplier, a carrier recovery. loop, a matched filter, and a decimator. The analog-to-digital converter oversamples an intermediate frequency (IF) signal from the tuner, and the Hilbert transform filter generates a Hilbert transform of the digital IF signal. An analytic IF signal can be generated from the digital IF signal by multiplying the Hilbert transform of the digital IF signal by j(=sqrt(−1)), and adding the resulting imaginary-valued signal to the digital IF signal. The sideband selection switch can “flip” the analytic IF signal by inverting the imaginary-valued signal. The complex multiplier multiplies the analytic IF signal by a complex-value sinusoid to shift the analytic IF signal to baseband. The resulting analytic baseband signal is match filtered and decimated to form a baseband double sideband signal with one sample per symbol period. The carrier recovery loop operates on the imaginary part of the analytic baseband signal to generate the complex sinusoid that shifts the analytic IF signal to baseband.

摘要： Satellite communications are carried out using the Data Over Cable Interface Specification (DOCSIS). Satellite modems are notified of upstream channel congestion by inserting a congestion notification message in a medium access protocol (MAP) message for the upstream channel. Specifically, the congestion notification message is inserted in an unused field of the MAP message, such as the explicit congestion notification (ECN) field. The MAP message can also carry other characteristics of the upstream channel, including priority threshold, multicast access burst availability, and available bandwidth.
