相比于传统单一接入功能终端以及多模终端,异构无线网络中的重构终端基于一个通用可重配置的软件无线电(SDR)平台实现不同接入功能,有效减少资源的利用。基于SDR分层设计思想,对终端调制解调重构实现建模进行研究。通过对四相相移键控信号(QPSK)和16QAM两种典型调制方式的调制解调重构仿真,并与传统终端进行比较,验证了所构建的终端调制解调重构模型的正确性,为终端重构实现技术的研究打下了基础。
Compared with the traditional single access terminal and the multi-mode terminal, the reconfigurable terminal in heterogeneous wireless networks implements different access functions based on a universal reconfigurable software-defined radio (SDR) platform, which effectively reduces resource utilization. Based on the SDR layered design idea, the terminal modulation and demodulation reconfiguration modeling is studied. Through the modulation and demodulation simulation of quadrature phase shift keying signal (QPSK) and 16QAM modulation and demodulation, and compared with the traditional terminal, verify the correctness of the terminal modulation and demodulation reconstruction model, Which laid the foundation for the research of terminal reconfiguration technology.
