Abstract: A communication device can be configured to detect false positives of a decoded signal that have passed error detection. The communication device can include an error detector and a false positive detector. The error detector can detect an error of a decoded signal generated from an encoded signal, and output a payload of the decoded signal in response to the decoded signal passing the error detection. The false positive detector can calculate an estimated bit-error rate (BER) of the encoded signal and a predicted BER of the encoded signal. The false positive detector can determine a false positive of the error detection passing of the decoded signal based on the estimated BER and the predicted BER.

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: 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.
