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...
A large body of computer-aided techniques has been developed in recent years to assist in the process of modeling, analyzing, and designing communica...
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...
The focus of this book is on developing computational algorithms for transmit wave- form design in active sensing applications, such as radar, sonar, ...
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...
