초록
We present a new transmit diversity downlink multiple input single output (MISO) timedivision multiplexing CDMA (CDMA/TDD) system using beamformer, Pre-RAKE diversity combining, and zero correlation duration (ZCD) orthogonal spreading sequence at basestation, while employing one matched filter (MF) based simple terminal receiver. Adopting techniques such as ZCD code, chip-level beamformer (CLB) array antenna configuration, Pre-RAKE transmit diversity, and one single matched filter at the receiver, the proposed system is shown to be efficiently applicable to various voice and data radio communication systems requiring very high performance guaranteeing nearly interference-free communications capability and simultaneously excellent receiver power efficiency. Therefore, it is expected that the proposed system can be efficiently applied to the emerging green communication system and its applications. © 2012 IEEE.
