ABSTRACT:
A method and apparatus are disclosed for detecting, in a plurality of stages of a matched filter, a binary convoluted coded signal having a plurality of code levels ranging from a low level, high repetition rate code to a high level, low repetition rate code, in which each filter stage of the matched filter is used to store elements of the convoluted coded signal in a memory such as a tapped delay line. The stored code is then tapped at intervals defined by the convoluted code to obtain a set of samples. The samples are then multiplied, each with a polarity coefficient determined by the convoluted code level at the tap locations resulting in translated samples. The samples are then summed in an adder to obtain an output signal. The output is connected to the input of the memory of a next filter stage of the matched filter and the sequence is continued for all the code levels in the signal.
