We consider pulse shaping in time-varying channels with statistical channel knowledge available at the transmitter. By establishing two optimization criteria for the optimality of joint transmitter and receiver pulse shapes, a new iterative pulse shaping scheme is presented yielding impressive gain in WSSUS scenarios. The approach is embedded in an(More)
The system is environment monitoring service based on Wireless Sensor Networks (WSN). Users can know temperature, humidity, light, and CO<sub>2</sub> level in real time. Excessive electricity consumption by lighting in the office can be saved and the quality of the office environment can become better by controlling lighting and CO<sub>2</sub> level.
