例句与用法
- S - cdma synchronous code division multiple access
同步码分复用 - Firstly , the basic principle of ocdma , the basic theory of ooc and the key technologies of ocdma are introduced . the development , research status and trends of ocdma technologies are also summarized . combining with other multiplexing technologies and using fiber gratings as the encoder / decoder are the trends of ocdma system
论文首先对ocdma的基本原理、光正交码的基本理论以及关键技术进行介绍,对光码分多址技术发展历史、研究现状以及发展趋势进行总结,指出同其它复用方式相结合的混合全光网络和采用光纤光栅编解码器是光码分复用技术最有希望的发展方向。 - The technology of direct sequence spread spectrum / code division multipul access ( dsss / cdma ) are applied in the broadband code division multiplex wireless communication systems , which means transmitting data at the rate of 2 . 048mbps using four e1 lines within the band of 20mhz . in this paper , the theory of the whole debice is first analysized specified for the system asic design and optimizing its performance
宽带码分复用无线传输系统是采用直接序列扩频/码分多址( dsss / cdma )技术，在20mhz频带内实现四路2 . 048mbps的e1链路数据速率的无线传输。本文首先分析了整个数传设备实现原理，针对系统asic设计和优化整机集成性能出发，提出并实现了基于fpga控制pm4314e1芯片的接口模块完成对e1链路信号的监控和告警功能的改进方案。 - The alternative solutions to upstream include wdma , tdma , cdma , and csma / cd , among which we adopt tdma at present . in this paper , existing dynamic bandwidth allocation ( dba ) scheme is introduced and a novel dba algorithm over qos is presented , which has fixed cycle , based on the self - similarity character of network traffic
可选方案有波分复用( wdma ) 、时分复用( tdma ) 、码分复用( cdma )和随机接入( csma / cd ) ,综合考虑各方面,目前采用的可行方案是时分复用方式。
