Abstract: An apparatus and method for short multipath mitigation. In one aspect the method comprises subtracting a first stronger path from a correlation function to obtain a first residual signal, wherein one component of the first residual signal is a weaker path; applying reconstruction on the first residual signal to obtain a first reconstructed weaker path; subtracting the first reconstructed weaker path from the correlation function to obtain a second residual signal; and applying reconstruction on the second residual signal to obtain a second stronger path. In one aspect, the apparatus includes an antenna for receiving a composite receive RF signal, a receiver front-end for converting the composite receive RF signal into a composite receive digital signal; and a processor for performing signal correlation on the composite receive digital signal to obtain a correlation function and for processing the correlation function to obtain a desired signal. In one aspect, the short multipath is identified by computing a Left Edge Height Ratio Indicator (LEHRI).
