【摘要】：5G移動通信技術(shù)相比于目前的4G移動通信技術(shù),其峰值速率將增長數(shù)十倍,達(dá)到吉比特。未來移動通信系統(tǒng)面臨著硬件成本高昂、系統(tǒng)功率消耗過高等問題,成為高傳輸速率通信的主要瓶頸之一。為了解決上述問題,學(xué)術(shù)界展開了對低功耗高效傳輸技術(shù)的研究,其中能夠有效解決上述問題的途徑之一就是低精度(如1~3 bit)ADC的接收機(jī)。通過對高斯信道下低精度量化的信道容量進(jìn)行分析,發(fā)現(xiàn)相較于傳統(tǒng)高精度ADC接收機(jī),2~3 bit的ADC所帶來的信道容量損失在可接受的范圍內(nèi)。面向低精度量化在無線通信系統(tǒng)中的應(yīng)用,綜合論述了低精度量化對信道容量的影響以及低精度量化下接收機(jī)的設(shè)計,解決了低精度量化下諸如同步、增益控制、信道估計等問題,為低精度量化通信系統(tǒng)的具體實(shí)現(xiàn)提供指導(dǎo)。
[Abstract]:Compared with the current 4G mobile communication technology, the peak rate of 5G mobile communication technology will increase tens of times to Gigabit.In the future, mobile communication systems will face the problems of high hardware cost and high power consumption, which will become one of the main bottlenecks of high transmission rate communication.In order to solve the above problems, the academic circles have carried out the research on the low-power and high-efficiency transmission technology, and one of the ways to solve these problems effectively is the receiver with low precision (such as 1 / 3 bit)ADC).By analyzing the channel capacity of low precision quantization in Gao Si channel, it is found that the channel capacity loss caused by the ADC of 2 ~ 3 bit is within an acceptable range compared with the traditional high-precision ADC receiver.For the application of low precision quantization in wireless communication system, the influence of low precision quantization on channel capacity and the design of receiver under low precision quantization are discussed synthetically, which solves the problem of synchronization and gain control under low precision quantization.Channel estimation provides guidance for the implementation of low-precision quantized communication systems.
