| 6. | Due to its simple structure , pioneer - net switch only needs to automatically identify " pioneer control token " and " channel cancel token " , used to establish and cancel channel
先锋寻径式交换机的构造简单，它只需自动识别由先锋网卡所发出的用于建立信道的“先锋信令”和撤消信道信令。 |
| 7. | Bits transmitted by every subchannel are determined by its value of signal to noise ratio ( snr ) , and the unwanted power caused by noise is distributed to every subchannel , so their damage is weakened
它根据各个子信道信噪比的情况确定其传送比特数，由噪声引起的干扰功率被分散到各个子信道中，降低了其引起的干扰。 |

| 9. | According to the information that reflected the condition of channel , this thesis classified acm into heuristic acm and snr - estimation acm . the system that using the first one of acm decide the scheme of modulation and coding according to the frame error ratio that reflected indirectly the condition of channel , while it using the another of acm decide the scheme according to the snr estimation
根据反映信道状态的信息不同,本文将自适应编码调制技术分为基于探索的自适应编码调制技术和基于信道信噪比预测的自适应编码调制技术,前者根据间接反映信道条件的误帧率和重传次数信息来决定编码调制方式,而后者根据信道信噪比预测的结果调节编码调制方案。 |
| 10. | The multistage constant modulus ( cm ) array is a cascade adaptive beamforming system that can recover several narrowband co - channel signals without training . the main idea of the smi - cma is to use smi to determine the initial weight for cma operation . the method can come up with the desire signal in despite of the interfering signal is stronger than the desire signal
基于以上考虑，我们提出了基于smi - cma联合自适应方法，该算法可以分离多个同信道信源，由smi算法决定cma算法的初始权向量，在干扰信号较强时，仍有稳定的sinr输出，具有较快的收敛速度。 |
