Abstract :
The broadcast and multicast service will play a major role in the future wireless communication. The enhanced broadcast and multicast system (EBCMCS) is the evolution of cdma2000 EV/DO in the broadcast system, and can provide the point-to-multipoint broadcast service. In this paper, the quadrature PN spreading and de-spreading methods in the EBCMCS of cdma2000 EV-DO are investigated, and a quadrature PN de-spreading method with lower complexity is proposed. Also, its complexity is compared with the traditional method. Finally, it is proved that the proposed method has much lower complexity than the conventional one without degrading the effectiveness.
