摘要：

While CDMA systems are proven to be excellent solutions for cellular communications, they suffer from severe multi-path interferences and are hard to support high-data-rate transmissions over firequency-selective fading channels. This letter introduces a novel downlink transmission method for next generation mobile communication systems. The proposed method can provide significantly improved performance in a hot-spot area while maintaining the backward compatibility with the 3rd generation CDMA systems.
