1. A method of analyzing a plurality of collected signal samples comprising:
- evaluating and obtaining information from at least some of the samples, the information identifies a source of at least one respective sample;
selecting a sample from the plurality;
synthesizing a representation of a portion of an expected signal from a respective source according to some of the obtained information; and
correlating at least a portion of the selected sample with the representation.

Abstract
A method and apparatus for identifying signal sources in a multi-source signal. Levels of signal components transmitted by each of the co-channel base stations in the area under test in a wireless network are measured and associated with the appropriate (originating) base station in the presence of co-channel and adjacent-channel interference without interrupting service by sensing and responding to received, variable, patterns.

21. A method comprising:
-
conducting a drive test;
collecting and storing a plurality of wireless signal samples during the drive test;
identifying, responsive to source information associated with members of the plurality, at least one signal source;
relative to a signal sample from the plurality, synthesizing an expected signal portion corresponding to the identified signal source; and
