Gain stabilization for radio intensity mapping using a continuous-wave reference signal

A Non-Sinusoidal Reference Wave for Pwm Ac Drives

In this paper we propose a suitable reference wave for Pulse Width Modulation (PWM) AC Drives. Staircase reference waves whose levels are calculated to eliminate certain harmonics are studied and a certain staircase reference waveform with L levels is constructed. When L is made very large in limit, this staircase waveform approaches a continuous one which is called Quasine (Quasi + Sine). This...

Efficient Radio Wave Front Propagation for Wireless Radio Signal Prediction

Due to the ever increasing complexity of wireless network design, wireless network simulation engines have become a necessary tool for wireless network engineers. A signal-strength prediction system lies at the foundation of every wireless simulator, making signal-strength prediction for microcells and picocells an important research topic in the radio field. Efficient and accurate methods are ...

Continuous-wave Square-wave (cwsw) Signal Generation and Peak Intensity Enhancement (pie) Analysis

WiFinder, a Wifi Signal Intensity Mapping Robot

The goal of the WiFinder project is to develop a robot that will find the strongest 802.11 signal in a room. In order to do this, the robot first maps out the 802.11 signal intensity using RSSI measurements, and then find the position of maximal signal strength intensity within the mapped area. In doing so, the robot implicitly solve the localization problem over a large, two dimensional grid. ...

Study of Ranging System Using Pseudo-Random Continuous Wave Signal

Pseudo-random signal has potential value as ranging system’s signal since it has noise-like character, excellent autocorrelation and large time bandwidth character. The theory of the ranging system based on pseudo-random signal and how system works will be introduced in detail in this paper. We learned that the quality of signal generated by pseudo-random signal generator is very good through o...
