22816 该文提出一种基于余数系统和有限域置换多项式的伪随机序列生成方法。 A method of generating pseudo-random sequence based on Residue Number System (RNS) and permutation polynomials over finite fields is proposed.
22817 该方法基于中国剩余定理将多个互质的小周期有限域随机序列进行单射扩展生成长周期数字伪随机序列，置换多项式的迭代计算在多个并行的小动态范围有限域上进行，从而降低了硬件实现中迭代环路的计算位宽，提高了生成速率。 This method extends several short period sequences into a long period digital pseudo-random sequence based on Chinese Remainder Theorem (CRT). Several short period sequences are generated by corresponding permutation polynomials over small finite fields parallelly, thereby reducing the bit width in hardware implementation and increased the generation speed.
22818 该文还给出构建长周期伪随机序列的置换多项式参数选择方法和中国剩余定理优化方法，在现有技术平台下可轻易实现 2100以上的序列周期。 In order to generate long period sequences, a method to find the permutation polynomial and the the optimazition procedure for CRT are also proposed in this paper. Based on most of current hardware platforms, the proposed method can easily generate the pseudo-random sequence with period over 2100.
22819 同时，该方法具有极大的迭代多项式选择自由度，例如仅在q º2(mod3) 且q £503 的有限域上满足要求的置换多项式就有 10905 种。 Meanwhile, this method has large space to select polynomials. For example, 10905 permutation polynomials can be used when  q º2(mod 3)   and  q £503 .
22820 硬件实现结构简单，基于 Xilinx XC7Z020 芯片实现 290的随机序列仅需 20 个 18 kbit 的 BRAM 和少量逻辑资源，无需乘法器，生成速率可达 449.236 Mbps。 Based no Xilinx XC7Z020, it only costs 20 18 kbit BRAMs and a small amount of other resources (no multiplier) to generate a pseudo-random sequence whose period over 290, and the generation rate is over 449.236 Mbps.
22821 基于 NIST 的测试表明序列具有良好的随机特性。 The results of NIST test show that the sequence has good random property and encryption performance.
22822 光和无线(Fiber-Wireless,  FiWi)混合网络可以有效解决“随时随地”接受高速业务的网络接入问题。 Fiber-Wireless (FiWi) hybrid network can effectively solve the problem that people need to receive high speed service anytime and anywhere.
22823 作为 FiWi 网络的关键节点，ONU 数目和位置很大程度上决定了网络的成本和性能。 As the key node of the FiWi network, the number and location of ONUs determine the cost and performance of the network to a great extent.
22824 为降低 FiWi 网络的建设成本，提升网络性能，该文基于 EPON-WIMAX 混合组网的 FiWi 网络，提出一种 ONU 部署策略，基于改进的遗传算法优化 ONU 部署，在使 ONU 数量最少的基础上，保证一定程度上的负载均衡。 In order to reduce the construction cost of FiWi network and improve network performance, an ONU deployment strategy based on improved genetic algorithm is proposed in the EPON-WIMAX hybrid network. It can minimize the number of deployed ONUs and take into account the load balancing.
