符号化速度
Examples
- In the proposed method , the controller takes the buffer length as congestion indication , takes sources quality and bandwidth utility as object function so as to learn on line . as the controller outputs , the coding rate for input traffic sources and the corresponding user percentage are used to adjust the cells " arrival rate to the multiplexer buffer . compared with the previous method where cells " arrival rate is tuned only by the encoding rate and the encoding rates for all input traffic sources are regulated in a body , the proposed method guarantee that the quality of cells are optimal while cell loss rate is minimized , which means quality of service is guaranteed
在该方法中，拥塞控制器以缓冲区大小信元作为拥塞指示，以信源质量和带宽利用率作为目标函数进行在线学习，控制器输出包括信源编码率及其对应的用户数在全部用户中所占的百分比，即根据信源编码率及对应的用户百分数调整信源输入流，从而克服了以往拥塞控制方法中仅仅调整编码率带来的对所有信源进行整体调整的缺陷，使控制系统在信元损失率最小情况下确保信源输入流质量最高，从而有效地利用了网络带宽。 - Lc apparatus almost meet all the needs of space optical communication such as weight , size , power consume , life , cost , driving voltage , intergration of optics and electricity , programe , optically take ? over aperture , beam scanning , deflexional range and so on . switches , deflexional facilities and scanning equipments which made with lc have been used in the system of labor in space communication . the only bug of lc apparatus is that their answer speed only get microsecond rate or submicrosecond rate . but it is practical for them to be used in special beam capture , scan , deflexion controling which don ’ t concerned with code rate and code type
液晶器件几乎满足空间光通信的所有大的指标要求如重量、尺寸、功耗、寿命、成本、驱动电压、光电集成、可编程性、光学接收孔径、光束扫描和偏转范围等等。液晶光开关、光偏转器、光扫描器已经开始应用于光纤通信的实验系统中。液晶类器件应用于光通信的唯一重大缺陷,是其响应速度目前只能达到微秒级或亚微秒级,不过,在不涉及到码型码率的空间光束捕获、扫描、偏转、控制方面,液晶器件完全可能进入实用化。 - We put the emphases on the soft output viterbi algorithm ( sova ) , which is one of turbo code ’ s decoding algorithms , and presents the derivation and computation step of the sova decoding algorithm . after presenting sova and map decoding algorithms and analyzing four kinds of decoding algorithms , the paper makes a comparison among the different decoding algorithms by emulation analysis , and analyzes the time complexity of various algorithms , and then contrasts them . in the last part of this paper , according to the criterion recommended by the consultative committee for space data systems ( ccsds ) , including code rate ,
根据空间数据系统顾问委员会( ccsds )为turbo码应用于深空通信系统推荐的标准,包括码率、码块大小、分量码类型、约束长度、码生成多项式,以及交织器的选择等参数的建议以及sova译码算法的理论基础,设计了sova算法的实现结构,通过仿真验证了本文所采用的turbo码的性能,从而证明turbo码确实是一种很好的信道纠错编码方式,它适用于要求功耗低或信噪比低的深空通信系统中。 - Future mobile communications have to support the transmission of high rate data and multimedia applications in the radio spectrum , which is already extremely scarce . the basic idea of adaptive coded modulation is to maintain a constant throughput by varying the transmitted power level , symbol transmission rate , constellation size , coding rate or any combination of these parameters . thus , without sacrificing bit - error rate ( ber ) , these schemes provide high average spectral efficiency by transmitting at high speeds under favorable channel conditions , and reducing throughput as the channel degrades
自适应编码调制( adaptivecodedmodulation , acm )的基本思想是在不牺牲系统传输性能(比如ber )为代价的前提下,通过单独改变发送功率、波特率、编码方案、码率、调制方式,或者是综合改变前面所述的各种参数,在有利的信道条件下,获得较大的吞吐量,当信道质量下将时,相应地降低传输速率,最终达到提高平均频谱效率的目的。 - The main results are as follows : 1 ) the influence of optical source chirp on femtosecond soliton interaction is studied numerically . results show that femtosecond soliton interaction with chirp from optical source is more serious than that without optical source chirp . the former can cause larger error code rate in soliton communication systems
