Future generations of wireless systems are designed for multimedia communication, with a wide range of data types and rates all sharing the same wireless infrastructure. In order to provide services with high capacity and desired quality of service, the system requires efficient resource allocation. In the system based on a code division multiple access technique, every user contributes to the interference characteristics of the system. This interference power is proportional to the transmitter power. It is clear that power control is the most important factor which allows more efficient resource sharing by balancing received signal quality and interference power
The multiple path connections idea is well-studied in the network layer of a wired infrastructure. Here we investigate a similar idea in the physical layer of a wireless access network. There is a major difference in the sense of channel existence. In the wired network, where the channels always exist, algorithms are based on smart queues and routings. In the physical layer of a wireless network, in contrast, channels are based on radio resource availability. Hence, based on the limited radio resource, we propose an opportunity-driven multiple connections scheme for resource sharing
The proposed scheme is studied under two different types of channels based on wideband code division multiple access standard, the dedicated channel and the common packet channel. The dedicated channel represents real-time traffic, while the common packet channel represents non-real-time traffic. Wideband code division multiple access technology is chosen because it has emerged as the most widely adopted third generation interface. The results obtained are encouraging. Even with a simple algorithm, capacity improvement from the proposed scheme can be seen
