A spread spectrum receiver uses a comparison of the magnitude of the code correlation
amplitudes at equal power at a one chip spacing to the magnitude at a central position
there between to determine if multipath interference is present. The lead or lag
error from constructive or destructive multipath interference may also be determined.
Inaccuracies due to such interference may then be corrected or minimized by, for
example, determining the residual code phase error and/or the prompt or accurate
code phase delay.
