characteristics of channel meaning in Chinese
通路特性
Examples
- Advances of studies on the biophysical characteristics of channels and acupoints
临床基础一体化的针刺规律研究 - The characteristic of channel , the mode of modulation and the methods of signal processing are main research contents in plc
本文涉及的电力线载波通信研究,主要有以下三个方面:信道研究、调制方式研究和信号处理研究。 - The characteristic of channel is the basic of plc research , including the transmission lines , channel noise , and attenuation . the ability of anti - jamming , speed and distance of transmission are decided by the mode of modulation . for example , the fsk , bpsk , cdma and ofdm are main modulations in the plc
信道的研究是根本,电力线通信其他研究内容都是建立在信道研究的基础上,内容主要包括传输线特性、信道噪声和信道衰减等;调制解调技术决定了电力线通信的传输速率、传输距离和抗干扰能力,它是电力线通信实现的关键,目前电力线通信中主要的调制方式有fsk 、 bpsk 、 cdma 、 ofdm等。 - The author considered great numbers of transmission characteristics of real channel in lms model and properly simplified it according to requirement in the project . the key characteristics in the model include multi - path fading , shadow fading , doppler shift , propagation noise , multi - path delay and and state transform of three status homogeneous markov chain described by lms model , etc . the key characteristics of channel are properly collocated and made to be the evidence theory of hardware implementation
Lms模型考虑了大量的实际信道传输特性,结合课题需求,实现过程中对lms模型做了适当简化,考虑了其中的多径和阴影衰落、多普勒频移、传播噪声、多径延迟以及lms模型所描述的三状态齐次markov链的状态转换等,对其所描述的主要信道特性适当组合,以此作为硬件实现时的理论依据。 - But the performance of the mimo system has deep relation with the properties of the multi - path signal in that environment , particularly affected by the correlation , the time spread and the azimuth spread of each path . therefore , in order to achieve potential huge capacity of the channel , gain prospective performance , choose appropriate system configurations and design excellent algorithms for signal processing , it is very important to realize and master the characteristics of channel in the indoor and the outdoor environment
而多入多出系统的性能,在很大程度上跟所处环境的多径信号性质有关,特别与各条路径之间的相关度、时延扩展和角度扩展有很大的关系,因此,了解和掌握户内和户外环境中无线多入多出信道的特征,对实现潜在的巨大信道容量、取得预期的性能、选择合适的系统结构和设计优良的信号处理算法至关重要。
