摘要
介绍了一种新的具有极高频带利用率的数字调制技术——最小波形差键控(VWDK),其可在不损失信噪比的前提下极大地压缩信号传输所需的频带。文中对VWDK的调制方式进行了理论分析,并给出了功率谱计算机仿真图。对VWDK的频带利用率进行估计,给出了VWDK传输系统设计方案。
VWDK,a new data modulation technique with high band efficiency is introduced.Using this technique,the frequency band needed for data transmission can be greatly compacted without loss of SNR.The theory of VWDK is explained and the simulation results are also presented.The band efficiency of VWDK is estimated and the design proposal for the VWDK transmission system is indicated.
