Continuous orthogonal spreading code based ultra-high performance array antenna system

摘要

Provided are a beamforming receiving/transmitting function and a beamforming receiving/transmitting structure, which are optimized for a given basic system in order to provide advanced performance in consideration of a wireless mobile communication system through a ultra-high performance CDMA array antenna based on continuously orthogonal spreading codes and a pre-rake scheme for non-interference communication. Also, there is provided a chip-level/symbol-level beamforming receiving/transmitting apparatus based on a multiple-input multiple-output (MIMO) system on a forward/backward link in order to be applied to various advanced wireless mobile communication applications by improving the performance and capacity of a Code Division Multiple Access (CDMA) array antenna system based on continuously orthogonal spreading codes and a pre-rake scheme for non-interference communication, and a forward and backward link automatic beamforming method. Accordingly, a ultra-high performance base station and terminal having no-interference reception performance as well as achieving high hardware and power efficiency may be realized.
