Abstract :
In this paper, we present a method for resolving a return multipath signal in the presence of very large noise. The method basically consists of choosing a function, whose correlation with the transmitted signal is either zero, or of an easily analyzed form. Hence, correlating such a function with the received signal will single out the noise component. An interesting feature of our approach is that large noise is not inherently disadvantageous. The paper describes the general method and then illustrate its application in some cases of general interest.
