CONTINUOUS ORTHOGONAL SPREADING CODE BASED ULTRA-HIGH PERFORMANCE ARRAY ANTENNA SYSTEM

摘要

PURPOSE: A high performance arrangement antenna system based on a successive orthogonal diffusion code is provided to modulate user signals by filtering pre-rake synthesis signals. CONSTITUTION: A beam forming unit(410) multiplies a weighted value vector corresponding to each antenna(401-1~401-M) by a pre-rake synthesis signal received by the antennas. The beam forming unit creates the reception beam of a chip level for the pre-rake synthesis signals according to each user. A reverse diffusing unit(460) modulates plural user signals by filtering the processed pre-rake synthesis signal.
