Title: Method and system for decoding convolutionally encoded codewords and soft decision output decoder
Inventor: VITERBI ANDREW J
IPC: H03M13/41
Filed: 1998-04-16
Granted: 2001-04-21
Abstract: A soft decision output decoder and decoding method. The decoder decodes a sequence of signals output by an encoder and transmitted over a channel. The soft decision output decoder includes a first ""generalized"" Viterbi decoder for decoding the sequence of signals received over the channel during a forward iteration through a trellis representing the encoder output having a block length T. The first ""generalized"" Viterbi decoder begins at an initial state t0 and provides a plurality of forward iteration state metrics Α for each state at each time interval over a window of length 2L, where L is on the order of a few constraint lengths and 2L is less than a block length T. A second ""generalized"" Viterbi decoder decodes the sequence of signals received over the channel during a backward iteration through the trellis. The second decoder starts at a second time t2L and provides a plurality of backward iteration state metrics β for each state at each time interval. A processor then performs a dual maxima computation at each state using the forward state metric, the backward state metric and the branch metric for same to provide a measure of the likelihood that a particular sequence of data was transmitted by the encoder. In the illustrative embodiment, the processor computes a log of the likelihood ratio using the forward and backward state metrics and the branch metrics for a selected state. This is achieved by first computing a max function as an approximation of the measure of the likelihood that a particular sequence of data was transmitted by the encoder. Then, a correction factor is computed for the approximation to provide a more exact measure of the likelihood that a particular sequence of data was transmitted by the encoder. In a specific embodiment, the correction factor includes an exponential function of the forward state metric and the backward state metric and the branch metric for a selected state. By performing forward and backward Viterbi decoding with dual maxima computations at each node within a window moved over the trellis, the inventive decoder provides the performance benefits associated with a LOG-MAP decoder while avoiding the excessive memory requirements of same.

Title: Method and apparatus for determining the rate of received data in a variable rate communication system
Inventor: STEIN JEREMY M
IPC: H03M13/35
Filed: 1998-11-30
Granted: 2001-09-01
Abstract: In an apparatus (200) for determining the rate of received data in a variable rate communication system, a decoder (230) decodes each frame of encoded data in a received signal at each possible data rate. The decoded data is processed by a cyclic redundancy check (CRC) element (240) to produce CRC bits. The data is reencoded and correlated by a correlator (234) with the received encoded data to produce a set of normalized correlation metrics. The decoded data may also be input to a Yamamoto detector (248) to Yamamoto quality metrics. Each operation is performed for each possible data rate. The normalized correlation metric for each rate is calculated from a correlation value and a constant computed for that rate. The correlation value is determined from a correlation of the demodulated soft frame symbols and the re-encoded frame. The highest normalized correlation metric is selected and the CRC bit for this data rate is checked. If the CRC checks, this data rate is indicated as the received data rate. Otherwise, the next highest normalized correlation metric is selected and the process continues. If no CRC checks, an erasure is indicated.
