ABSTRACT:
A method of cancelling interference induced by a coherent interference source in a spread spectrum receiver comprising the steps of: quantifying (44; 94) first interference values induced by the coherent interference source (SCH) in symbols on a first spread spectrum physical channel (P-CCPCH; CPICH); calculating (46, 48, 50; 96, 98, 100) second interference values induced by the coherent interference source in symbols on a second spread spectrum channel (DPCH) from the first interference values; and applying (18; 74) a correction value, derived from the second interference values, to the symbols on the second spread spectrum channel.
