摘要： A channel detector has an anchor points inserter, a desired signal calculator, a distance calculator and a data detector. The anchor points inserter is adapted to choose values of expected transition locations for transition shifts within a received signal and to insert anchor points corresponding to the chosen values within a bit detection interval. The desired signal calculator is coupled to the anchor points inserter and is adapted to estimate desired signals corresponding to transition location information from the anchor points inserter. The distance calculator is coupled to the desired signal calculator and is adapted to generate a distance calculator output based on distances between the received signal and each of the desired signals. The data detector is coupled to the distance calculator and is adapted to identify a bit sequence corresponding to a desired signal having a minimum distance from the received signal. The data detector is adapted to generate an output based on the distance calculator output.
