    摘要： System and method of comparing-selecting state metric values for high speed. Viterbi decoding. In an Add-Compare-Select (ACS) unit, a select-control signal is produced by Boolean operations on comparator decision signals and used to control a multiplexer structure. The comparator decision signals can be generated in parallel by an array of comparators comparing all possible pairs of a set of state metrics values. The Boolean operations are predefined through Boolean algebra that uses the decision signals as variables and complies with restriction imposed by the selection criteria, e.g., to select an minimum or maximum value of the set of state metrics values. The Boolean operations are performed by a logic module implemented using basic logic gates, such as AND, OR and NOT. As a result, the multiplexer structure that receives the set of input values can output the optimum value responsive to the select control signal.

    摘要： There is provided a computer-implemented method of estimating transmitted signals in a communication system, the signals being transmitted by a transmitter to a receiver over a communication channel having a channel response, the method comprising estimating the transmitted signals based on generated trial sequences minimizing the channel response between adjacent received signals. There is also provided a receiver, a signal detector device and a communication system adapted to estimated transmitted signals in a communication system by generating trial sequences and determining the generated trial sequences minimizing the channel response between adjacent received signals. The present invention is particularly adapted for OFDM communication systems.
