Abstract

A method for testing a receiver in a code division multiple access (CDMA) communications system. Frequency spectrums for each of a plurality of provided CDMA code patterns (31) are generated (35) and phase shifted (36), before being combined (37) to generate a constellation spectrum. The constellation spectrum is converted 38 to a time domain constellation signal which can be injected (33) into a CDMA receiver under test. The method allows for fast and cost-effective synthetic generation of constellation signals that are particularly suited to testing global navigation satellite system (GNSS) receivers. Also relates to apparatus for providing the same.
