Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model shows the basi ...

The Blinky project is a simple program for the LPC2138using Keil MCB2130 Microcontroller Board.
It blinks the LEDs at speed according to the Potentiometer setting and prints the current seting to the Serial Port 1.In addition it generates a sine wave with an adjustable frequency on ...
论文 A Rate Adaptive Channel Estimation Approach
In this paper, we consider the channel estimation
problem in Millimeter wave (mmWave) wireless systems with
large antenna arrays. By exploiting the inherent sparse nature of
the mmWave channel, we develop a novel rate-adaptive channel
estimation (RACE) algorithm, which can adaptively adjust the
numb ...
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STC8A系列单片机的高精度频率计设计
介绍了一种基于STC8A4K64S2A12单片机的高精度频率计的设计方案,可实现幅度为20mV~5V,频率为1Hz~10MHz方波、正弦波及三角波的测量。该频率计利用此系列单片机的内置比较器,将小信号转变为同频率的TTL/CMOS电平,直接进行测量。同时,根据各计数器溢出会使单片机对应端口发生电平反转的特性,将定时器级联实现了内部全自动的高精 ...
