摘要:
For coherent fiber optic communications, the nonlinear XPolM impairment is the most important issue to realize over-100 Gbps high-speed transmissions. A method provides a way to cancel time-varying XPolM crosstalk by introducing multi-stage adaptive mechanism. In the method, a low-complexity adaptive filtering based on recursive least-squares (RLS) first tracks the time-varying crosstalk along with the per-survivor trellis-state decoding. The estimated channel and the decoded data are then used to calculate the empirical covariance, which is in turn exploited to obtain more accurate channel estimates by means of optimal-weighted least-squares. This is performed with a low-complexity processing over frequency domain with fast Fourier transform. The performance is significantly improved with turbo principle decoding, more specifically, iterative decoding and iterative estimation over a block.

Systems and methods are disclosed for synchronizing sequence numbers in a packet flow. One such method includes receiving a sequence number synchronization request from a redundancy peer. The sequence number synchronization request is associated with a packet flow. The method also includes incrementing by a fixed amount a packet sequence number for the packet flow, after the sequence number synchronization request. The method also includes transmitting a next packet including the incremented packet sequence number to the communication peer.

摘要:
This invention relates to methods comprising administering to a subject a dietary composition for modifying cellular metabolism, metabolic production of reactive oxygen species and the resulting level of reactive oxygen species. The invention is drawn to a method comprising a combination of carnitine, lipoic acid and polyphenol, which has the effect of enhancing metabolism and reducing oxygen species at the same time. The invention is also drawn to a method of oral administration of carnitine, lipoic acid and polyphenol to a mammalian host, at an effective dose necessary to affect enhanced metabolic processes and reduced oxygen species in animals including humans.
摘要:
One example embodiment includes a testing device. The testing device comprises a signal reception element, an out-of-band detector and testing logic. The signal reception element is configured to receive a physical layer signal from a communication module via a physical link and to produce an incoming double modulated signal, the incoming double modulated signal including a high-speed data signal and an out-of-band data signal. The out-of-band data signal comprises diagnostic data of the communication module. The out-of-band detector is coupled to the signal reception element and is configured to extract the out-of-band data signal from the incoming double modulated signal. The testing logic is coupled to the out-of-band detector and is configured to extract and analyze the diagnostic data from the out-of-band data signal.
