14488 针对无线网络中资源受限的组播路由问题,考虑网络节点的节点度限制和网络链路的带宽约束,以最小化组播路由开销为目标,提出了一种二进制编码方式的基于灰狼优化算法的组播路由策略。 For the resource－limited multicast routing problem in wireless networks，a binary－coding based multicast routing strategy is proposed by using the Grey Wolf Optimizer( GWO) algorithm，which aims to minimize the cost of multicast routing and satisfy both the node degree limitation and link bandwidth requirement．

14491 针对四维直接序列扩频调制信号的峰均比（Peak-to-Aaverage Ratio, PAPR）问题,分析了成形滤波器滚降因子对调制信号PAPR的影响,得到了PAPR随滚降因子的变化规律,进一步引入了基于限幅的PAPR抑制方法降低调制信号的PAPR。 The rule about the peak－to－average ratio( PAPＲ) of four－dimensional direct sequence spreadspectrum( DSSS) modulated signal is obtained，which reveals the relationship between the signal PAPＲand the roll－off factor of the shaping filter． The influence of roll－off factor of shaping filter on the modulated signal PAPＲ is analyzed，and the clipping－based PAPＲ suppression method is further introduced to reduce the modulated signal PAPＲ．
14492 理论和仿真结果表明,当滚降因子为0.42时,调制信号的PAPR值最小;所引入的PAPR抑制方法能有效降低调制信号的PAPR,同时对系统误码性能的影响极小,当限幅率为4、系统互补累积概率密度为0.1%时,调制信号PAPR降低了0.8 dB,系统误码率为10-5所对应的信噪比损失仅为0.3 dB。 Theoretical and simulation results show that when the roll－off factor is0． 42，the PAPＲ value of the modulated signal is the smallest; the PAPＲ suppression method introducedcan effectively reduce the PAPＲ of the modulation signal，and has little impact on the system bit error performance． When the clipping rate is 4 and the system complementary cumulative probability density is0． 1% ，the PAPＲ of the modulated signal is reduced by 0． 8 dB，and when the bit error rate is 10－5，thesignal－to－noise ratio loss is only 0． 3 dB．
