Abstract: A system, method and device for error detection/estimation in OFDM communications systems is proposed. The disclosed mechanism allows an efficient error prediction in a received packet, without having to perform full FEC decoding of the packet that could impair the overall latency of the system due to the time spent in a complete FEC decoding of the packet. In order to do that, it generates a decision variable with the aim to check whether a received packet has errors or not, after performing only partial FEC decoding of the packet, without either resorting to the use of error-detection codes.

Abstract: A physiologic transmitter manages multiple communications between physiologic data acquisition devices attached to the patient and a receiver attached to an MRI or CT scanner. The transmitter's processor is able to generate waveform data and trigger data based upon the acquired physiologic data and transmit the data to a physiologic receiver attached to the host scanner. The receiver then is able to deliver a trigger signal to the host scanner for imaging the patient during a selected time frame based upon cardiac and/or respiratory cycles of the patient.

Abstract: Methods and apparatus are disclosed for estimating a quality of a received data frame in a trellis decoder. The decoder utilizes a trellis diagram to depict the states and stages the decoder transitions through in search of a sequence of bits that closely resemble the received sequence. In the trellis diagram, each state at one stage is connected to a state at the next stage by a branch and a group of connected branches form a path. The decoder selects a winning path by comparing path metrics computed for each of the paths in the trellis diagram and outputs a most-likely sequence of hard bits from the winning path. A count of non-ideal branches over the winning path can be used for calculating the frame quality of the received data frame or the burst quality of a data burst in the received data frame.

Abstract: This disclosure describes techniques for operating a client device to communicate with a wireless access point to validate data within a frame by comparing channel quality metrics and duration metrics to thresholds. Information received within a validity window may be treated as correctly received even if the frame fails a subsequent verification process or if reception of the frame is terminated prior to the end of the frame.

Abstract: By utilizing Reed-Solomon erasure decoding algorithms and techniques, the system is able to perform error detection for the case where the number of bytes received in error exceeds a correcting capability of a decoder. The error detection can be used, for example, to determine whether a codeword is decodable, and whether the retransmission of data is necessary. The retransmission can be accomplished by assembling a message that is sent to another modem requesting retransmission of one or more portions of data, such as one or more codewords.

Abstract: In described embodiments, data pattern-based detection of loss of signal (LOS) is employed for a receive path of serializer/deserializer (SerDes) devices. Pattern-based LOS detection allows for detection of data loss over variety of types of connection media, and is generally insensitive to signal attenuation. More specifically, some described embodiments disclose reliable pattern-based detection of LOS across different connection media for incoming receive data when discreet time decision feedback equalization (DFE) is employed.
