It has been suggested1 that an appropriate figure of merit for a low probability of intercept and
detection (LPI/D) waveform is the quantity “Range x Bandwidth / Joule”. That is, the further the
range, the wider the bandwidth and the less amount of energy used to achieve these values, the
more cov ...

A large body of computer-aided techniques has been developed in recent years to assist
in the process of modeling, analyzing, and designing communication systems . These
computer-aided techniques fall into two categories: formula-based approaches, where the
computer is used to evaluate complex formu ...
论文 基于频率插值的4.0kbps 语音编码器的性能和设计（英文）
The 4.0 kbit/s speech codec described in this paper is based on a
Frequency Domain Interpolative (FDI) coding technique, which
belongs to the class of prototype waveform Interpolation (PWI)
coding techniques. The codec also has an integrated voice
activity detector (VAD) and a noise reduction capabi ...
书籍 Waveform Desig
The focus of this book is on developing computational algorithms for transmit wave-
form design in active sensing applications, such as radar, sonar, communications and
medical imaging. Waveforms are designed to achieve certain desired properties, which
are divided into three categories correspondin ...
技术资料 基于UCC28019的PFC电路设计
为设计高效率、低损耗的PFC电路,本文基于UCC28019进行电路设计。以UCC28019输出的PWM波形来控制Boost升压斩波为核心电路,使电路中的电容交替地充放电、电感交替的储存和释放能量,最后实现在输入AC20V~24V电压情况下稳定输出DC38V。测试结果表明,系统实现效率为95%左右,电压调整率小于1%,电源功率因数0.99。交流输入电压为19 ...
技术资料 基于ICL8038等构成的函数发生器电路
摘要：本系统以ICL8038集成块为核心器件，制作一种函数信号发生器，制作成本较低。适合学生学习电子技术测量使用。ICL8038是一种具有多种波形输出的精密振荡集成电路，只需要个别的外部元件就能产生从0.001Hz~30KlHz的低失真正弦波、三角波、矩形波等脉冲信号。输出波形的频率和占空比还可以由电流或电阻控制。另外由于该芯 ...
