Forward link partial-balance power control algorithm for W-CDMA communication

Abstract

Balance power control is based on the idea of balancing Carrier to Interference Ratio (CIR) of all wireless links. Unbalance power control means that different traffics can achieve different CIR at receivers. This paper proposes a forward link partial-balance power control algorithm, which can provide necessary Quality of Service (QoS) for multimedia traffics in Wideband CDMA(W-CDMA) systems. The proposed algorithm is the integration of grading traffics priority and allocating and adjusting forward link power levels. For higher priority traffics, the unbalance power control is used. Whereas for lower priority traffics, balance power control is adopted. Computer simulation results show that the proposed algorithm can guarantee the special QoS requirements of the traffics with higher priority orders and maximize the CIR of the traffics with lower priority orders.

Improvement of interfacial adhesion between PBO fibers and cyanate ester matrix

“…Therefore, many efforts have been devoted to improve the surface wettability of PBO fibers and enhance the interfacial adhesion between PBO fibers and resin matrix . Various techniques including plasma treatment, acid treatment, and coupling agent treatment were employed to make the surface of fibers rough or introduce polar functional groups onto the surface of fibers. For example, Wang et al and Zhang et al studied the effects of plasma treatment on surface properties of PBO fiber.…”
