Abstract
An apparatus for determining multipath correlations among a search range of input data, and a method thereof. The multipath searcher comprises a pseudo noise (PN) code generator, a correlator, and a data combiner. The PN code generator generates a first PN code corresponding to a first multipath component of the input data, postpones a first period based on the search range, then generates a second PN code corresponding to a second multipath component of the input data. The correlator is coupled to the PN code generator, and correlates the input data with the first PN code and the second PN code to produce a first correlation and a second correlation. The data combiner is coupled to the correlator, receives the first and the second correlations to determine a primary multipath component with a higher correlation thereto.
