Spread spectrum communication receiver

摘要

A spread spectrum communication receiver includes a transmission path state estimating unit which estimates states of paths from a received signal, and demodulator units independently performing demodulation processes on signals propagated through the respective paths. A symbol combiner combines output signals of the demodulator units. A decision unit is directly or indirectly coupled to the symbol combiner and makes a decision on an output signal of the symbol combiner. An unnecessary component eliminating unit eliminates a component of a first symbol which is an unnecessary component that is propagated through one of the paths and overlaps with a received component of a second symbol to be demodulated, so that the unnecessary component has been eliminated from the output signal of the decision unit.
