NTACS Narrowband Total Access Communication System

用法例句

Based on RS coding and transforming high-order waveform modulation,this paper proposed a solu- tion to make the best of channel bandwidth and signal power and reduce the receiver demand to the SNR,using this technique in the narrow band communication system,then analyzing the performance in matlab.

本文采用 RS 编译码+高阶波形编码调制解调的方法,设计有效利用信道带宽和信号功率而又提供有效降低接收信噪比的新型调制解调方案,并将其应用于窄带通信系统,通过 Matlab 仿真分析其性能。

As a result, we should consider balancing the efficiency and the reliability, and design the high-speed communication systems in limited transmission bandwidth, which .

因此在本文第三章，引入连续相位调制技术(CPM)来结合TCM技术从而进一步提高频带的利用率，达到效率和可靠性的最优结合，这一技术为窄带高速无线通信系统提供了有效的解决。
