To solve the problem that the spectrum spread rate is held in the clock period. A method based on the Balance Gold Sequences (BGS) is presented in Ultra-Wide Band communications. The theoretical bit error rate (BER) performance is deduced after building a mathematical model for the system. Computer simulation shows that the Balance Gold Sequences can obtain(More)
—With the rapid development of wireless communications, various wireless networks will coexist. UMTS and WLAN, a popular and representative interworking paradigm, provides a plethora of multimedia services to mobile users with multimode access capability. In this paper, we propose an effective call admission control (CAC) scheme which is based on bandwidth(More)
To solve the problem which the spectrum spread rate is held in the clock period and the sequence length of address code lies on the quotient of clock rate with information rate. A method which is based on the Balance Gold Sequences (BGS) is presented in Ultra-Wide Band communications. After presenting a mathematical model for the system, the theoretical bit(More)
