With such a mechanism, each department is charged only for using extra bandwidth rather than being billed for a larger, nailed-up circuit, regardless of use. 有了这样的一个机制,每个部门只按使用超额的带宽计费,而不是不管用不用都按更大的、定死的电路计费。
Combined with spatial diversity, space-time coding can provide high data rates and good performance without extra bandwidth demand. 结合空间分集,空时编码在不增加信道带宽的情况下能提高系统的传输速率,达到良好性能。
The AM technology is a tradeoff between reduction of multicast trees and extra bandwidth waste. 因此,聚合组播是组播树数量减少和额外带宽(EB)浪费的一种折中。
Extra bandwidth is needed to transmit the original video and related information in full-reference and reduce-re ference methods. 由于全参考型和部分参考型评价方法都需要额外的带宽来传输原始视频及相关信息,其实用价值非常有限。
Software antenna technology can increase capacity of wireless communication system greatly without extra bandwidth. Thus, it is a next generation wireless technology with bright prospect. 软件天线技术能够在不改变信号带宽的情况下提高通信系统的容量,是一种很有前景的下一代通信技术。
