Preferably channel estimation is accomplished in the time domain using a locally generated reference signal. The channel estimator generates an initial estimate from a cross correlation between the time domain reference signal and an input signal input to the receiver and generates at least one successive channel estimate. Preferably the successive channel estimate is determined by vector addition (or subtraction) to the initial channel estimate. The at least one successive channel estimate reduces the minimum mean square error of the estimate with respect to a received signal. | 2015-11-19 |
20150333934 | METHOD AND APPARATUS FOR CHANNEL ESTIMATION - To facilitate sending a reference signal in a wireless communication environment, a transmitter sends a reference signal in a first time-frequency resource to a user equipment (UE); the transmitter sends data information in a first portion of a second time-frequency resource different from the first time-frequency resource to the UE; and the transmitter excludes data information from being sent in a second portion of the second time-frequency resource. The second portion of the second time-frequency resource is designated for use by another transmitter for sending another reference signal to the UE. | 2015-11-19 |
20150333935 | PoDL SYSTEM WITH ACTIVE dV/dt and dI/dt CONTROL - A Power Over Data Lines (PoDL) system includes Power Sourcing Equipment (PSE) supplying DC power and differential Ethernet data over a single twisted wire pair to a Powered Device (PD). Due to start-up perturbations, PD load current variations, and other causes, dV/dt noise is introduced in the power signal. Such noise may be misinterpreted as data unless mitigated somehow. Rather than increasing the values of the passive filtering components conventionally used for decoupling/coupling the power and data from/to the wire pair, active circuitry is provided in the PSE, PD, or both to limit dV/dt in the power signal. Such circuitry may be implemented on the same chip as the PSE controller or PD controller. Therefore, the sizes of the passive components in the decoupling/coupling networks may be reduced. | 2015-11-19 |
20150333936 | COMMUNICATION APPARATUS AND METHOD FOR HIGH EFFICIENCY SATELLITE SERVICE - Disclosed are a communication apparatus and a communication method capable of improving transmitting/receiving frequency efficiency of a satellite signal per bandwidth or spectral efficiency (S.E) per bandwidth by removing and improving a distortion or inter-symbol interference for applying a minimum-mean square error (MMSE) equalizer required to detect a frame synchronization and a modulation code rate in a satellite service for satellite broadcasting or communication under the variable coding and modulation (VCM) or adaptive coding and modulation (ACM) environment. | 2015-11-19 |
20150333937 | DECISION FEEDBACK EQUALIZER - In a decision feedback equalizer, at least one of weighting devices that has a tap coefficient an absolute value of which is relatively larger than absolute values of tap coefficients of other weighting devices is referred to as a main weighting device, and delay elements are disposed asymmetrically on signal processing paths or updating paths of the to coefficients of the weighting devices in such a manner that an updating interval of the tap coefficient of the main weighting device is shorter than updating intervals of the tap coefficients of the other weighting devices. | 2015-11-19 |
20150333938 | OFFSET AND DECISION FEEDBACK EQUALIZATION CALIBRATION - A decision feedback equalizer is calibrated to compensate for estimated inter-symbol interference in a received signal and offsets of sampling devices. The decision feedback equalizer is configured so that an output signal of a sampling circuit represents a comparison between an input signal and a reference of the sampling circuit under calibration. An input signal is received over a communication channel that includes a predetermined pattern. The predetermined pattern is compared to the output signal to determine an adjusted reference for configuring the sampling circuit that accounts for both offset and inter-symbol interference effects. | 2015-11-19 |
20150333939 | Efficient Tracking of Decision-Feedback Equaliser Coefficients - Efficient methods and apparatus for tracking decision-feedback equaliser (DFE) coefficients are described. In an embodiment, updated coefficients for a feed-forward equaliser (FFE) are generated using conventional methods and then these are used, along with an averaged updated value of channel impulse response (CIR) estimate to generate updated DFE coefficients. In an embodiment, the updated DFE coefficients are generated by multiplying the updated CIR estimate (in the frequency domain) and the updated FFE coefficients (also in the frequency domain). The resultant updated DFE coefficients in the frequency domain may then be converted into the time domain before outputting to the DFE. | 2015-11-19 |
