Abstract: Systems and methods for performing high-speed multi-channel forward error correction using external DDR SDRAM is provided. According to one exemplary aspect, an interleaver/deinterleaver performs both read and write accesses to the DDR SDRAM that are burst-oriented by hiding active and precharge cycles in order to achieve high data rate operations. The interleaver/deinterleaver accesses data in the DDR SDRAM as read blocks and write blocks. Each block includes two data sequences. Each data sequence further includes a predetermined number of data words to be interleaved/deinterleaved. The PRECHARGE and ACTIVE command for one data sequence is issued when a preceding data sequence is being processed. Data in one read/write data sequence has the same row address within the same bank of the DDR SDRAM.

Abstract: In a communications system, such as a Power-Over-Ethernet system, where power supply equipment (PSE) supplies power to powered requiring devices (PRDs), a system and method of dynamic power management is implemented. The system and method monitors the power consumed at each port by the PRDs. Based on this monitoring, the PSE dynamically determines the minimum power which can be allocated to each PRD, and so dynamically maximizes the available reserve power. The PSE maintains a queue or queues wherein PRDs are listed in order of a power allocation priority. When additional power is available, the PSE preferentially allocates power to a PRD or PRDs which have higher priority. The system and method of the present invention minimizes the power allocated to each individual network device, as a result of which the total number of network devices that can be supported with the available power may be maximized.

Abstract: Aspects of a method and system for detecting enhanced relative grants in a wireless communications system may include determining one or more signed signal power levels, wherein the one or more signed signal power levels may be positive E-RGCH signal levels or negative E-HICH signal levels. A probability density function may be estimated from the determined one or more signed signal power levels, and a decision threshold based on the estimated probability density function may be set. The probability density function may be estimated based on symmetry of the probability density function. The decision threshold may be set to achieve a desired probability of false positive detections. The decision threshold may be used to distinguish a received HOLD signal from a received DOWN signal for an E-RGCH channel, or to distinguish a received DTX signal from a received ACK signal for an E-HICH channel.

Abstract: A communication receiver includes a front end, which is arranged to receive a Radio Frequency (RF) signal, which includes modulated symbols carrying data that have been encoded by a block Forward Error Correction (FEC) code. The front end converts the RF signal to a sequence of soft received symbols, wherein the soft received symbols are subject to distortion by at least first and second noise components having respective at least first and second statistical distributions. A metric calculation unit is arranged to process the soft received symbols so as to extract parameters indicative of the at least first and second statistical distributions, and to compute FEC metrics based on the extracted parameters. A FEC decoder is arranged to accept the FEC metrics as input, and to process the metrics in an iterative FEC decoding process so as to decode the FEC code and reconstruct the data.

Abstract: A system and method is provided for phase interpolator based transmission clock control. The system includes a transmitter having a phase interpolator coupled to a master timing generator and a transmission module. The phase interpolator is also coupled to a receiver interpolator control module and/or an external interpolator control module. When the system is operating in repeat mode, the transmitter phase interpolator receives a control signal from a receiver interpolator control module. The transmitter phase interpolator uses the signal to synchronize the transmission clock to the sampling clock. When the system is operating in test mode, a user defines a transmission data profile in an external interpolator control module. The external interpolator control module generates a control signal based on the profile. The transmitter phase interpolator uses the signal to generate a transmission clock that is used by the transmission module to generate a data stream having the desired profile.

In an example, a first subset of the plurality of the WECs is co-located on a first chip, and a second subset of the plurality of the WECs is co-located on a second chip. The first chip and the second chip may be located in a single device or in separate devices.

Abstract: As additional channels are added to a communication system for applications, such as standard density (SD) and eventually high density (HD) Video on Demand (VOD), additional capacity can be realized by reducing the time required to transmit content. A reduction of transmission time (or an increase of the transmission rate) can be achieved by bonding channels of the communication system. The bonded channels typically provide a statistical multiplexing gain because the additional bandwidth is treated as a large single channel for the download. Bonding channels of the communication system can provide high speed downloading of content, such as video content, far in excess of the playback rate. Using bonded channels can relax the Quality of Service (QoS) requirements of a data stream, such as a video stream, over an internet protocol (IP) network.
