Abstract
This invention is a spread spectrum receive apparatus comprising a plurality of receive branches, wherein each of the plurality of receive branches includes at least one antenna which receives a plurality of different polarized components, and a RAKE receiver, commonly prepared for the plurality of receive branches, for modulating the plurality of different polarized components received, and outputting a modulated signal based on the plurality of different polarized components modulated.
Claims11
A spread spectrum receive apparatus comprising:
- a plurality of receive branches respectively configured to receive a plurality of different polarized components with each other;
- A/D converters configured to convert the received plurality of different polarized components which are directly received from the plurality of receive branches to digitalized plurality of different polarized components, respectively;
- a RAKE receiver, commonly prepared for said plurality of receive branches, configured to demodulate the digitalized plurality of different polarized components which is directly received from the A/D converters, and to output a demodulated signal based on the plurality of different polarized components demodulated;
- and
- a delay device configured to delay at least one of the plurality of different polarized components from said plurality of receive branches to the RAKE receiver.
