在混合调度模型中,对异步虚拟信道提出了基于遗传-粒子群排序的调度算法,业务优先级、调度时延紧迫度及帧剩余量紧迫度是影响虚拟信道调度先后顺序的关键约束。 |
In the model, a algorithm based on genetic-particle swarm ordering is proposed for asynchronous VirtualChannel (VC). Service priority, scheduling delay urgency and frame remaining urgency are the key constraintsthat affect the scheduling order of VC. |

该算法根据约束建立了遗传-粒子群适应度函数模型,进一步使粒子群体内的粒子根据遗传算法的进化算子进行位置更新,从而找到最优的异步虚拟信道调度顺序。 |
The algorithm establishes the genetic-particle swarm fitness functionmodel according to the constraints, and further enables the particles in the particle swarm to update theposition according to the evolution operator of the genetic algorithm, thereby finding the optimal asynchronousVC scheduling sequence. |

同时,对同步虚拟信道设计了动态加权轮询调度算法,使各同步虚拟信道按照加权因子和分配的时隙数,轮流占用物理信道。 |
At the same time, a dynamic weighted round-robin scheduling algorithm is designed forthe synchronous VC, so that each synchronous VC occupies the physical channel according to the weightingfactor and the allocated number of time slots. |

仿真结果表明,该文的虚拟信道混合调度算法兼顾了异步数据的优先性、同步数据的等时性和VIP数据的紧迫性,具有更小的平均调度时延和更少的帧剩余量,满足不同业务的传输要求。 |
Simulation results show that the VC hybrid scheduling algorithm in this paper takes into account the priority of asynchronous data, the isochronism of synchronous data, and the urgency of VIP data. It has a smaller average scheduling delay and less frame remaining, so the algorithm meets the transmission requirements of different services. |

为了应对直接序列扩频(DSSS)中信息传输率低的局限,出现了多进制扩频及索引调制等技术。 |

由于此系列技术中附加信息都是通过伪码变换来映射的,因此调制阶数越大,复杂度也越大,而当系统所承受的复杂度受限时,调制阶数也就无法提升。 |
Because the additional information in this series of technologies is mapped by pseudo code transformation, the larger the modulation order is, the greater the complexity will be, and when the complexity of the system is limited, the modulation order will not be improved. |

为解决高阶信息传输率受限问题,该文提出一种低复杂度的超高阶码索引调制(UHO-CIM)方法。 |

通过2维信息的分组来进行多码集索引,从而降低通道数量,进而通过3维信息的分组来进行循环移位索引,从而在不增加通道情况下大幅度地提高传输率,而且利用移位通道和非移位通道关系,去除环境影响。 |
The multi code set index is carried out by two-dimensional information grouping, so as to reduce the number of channels, and then the cyclic shift index is carried out by three-dimensional information grouping, so as to improve greatly the transmission rate without increasing the channels. Moreover, the relationship betweenshift channel and non-shift channel is used to remove the environmental impact. |
