Design of Frequency Synthesizer for Shortwave Band Frequency Hopping Based on DSP modulator carrier 色度副载波基准频率基于DSP的短波跳频频率合成器的设计
The frequency prediction of skywave propagation in shortwave band is the precondition of performance prediction of skywave communication circuit. 短波天波传播频率预测是短波天波通信电路性能预测的前提。

Analysis of the Narrow Band Precondition about MUSIC Algorithm in the Shortwave Band 短波段内多重信号分类算法的窄带假设分析
In the shortwave band especially, the actual sizes of antennas are mostly large, that is also a difficult problem to achieve the goal of antennas ' miniaturization. 尤其在短波波段(SWB),天线的实际尺寸都较大,短波天线的小型化也就难以实现。
