Patent ID: 8144823

Claim:
A signal processing device, comprising: a plurality of receiving devices for receiving an original signal stream to generate a set of signal streams, wherein each of the set of signal streams corresponds to a phase; a storage module, coupled to the plurality of receiving devices, for storing a plurality sets of signal streams generated by the plurality of receiving devices at a plurality of times; a weighting module, coupled to the storage module, for selecting a reference signal stream according to the set of signal streams to which each time corresponds, the reference signal stream corresponding to a reference phase, the weighting module generating a set of rotated signal streams to which each time corresponds according to the reference phase and the set of signal streams, and generating a set of weighting signals according to the plurality sets of rotated signal streams of the plurality of times; and a processing module for generating a set of weighting signal streams according to the set of weighting signals and the plurality sets of signal streams.
