| dc.description.abstract | This project aims at implementing a synchronous data communication system using the ultrasonic waves as carrier. The ultrasonic waves enable to overcome the problem of interference due to the external audio sources, which can be quite a nuisance if ordinary sound waves are used. The input to this system is from keypads and the output is displayed on a liquid crystal display (LCD). Any input to the system is encoded in a scheme, and then it is modulated and transmitted through the wireless medium. When this scheme is received, it is demodulated and data is decoded and is displayed. The digital data is transmitted using modulation and demodulation techniques for efficient utilization of the communication channel. For this reason Frequency Shift Keying (FSK) modulation and demodulation techniques have been chosen. The modulators and demodulators of this scheme have been designed. For reliable communication, a simple protocol is implemented which handles synchronization between either ends of the system. | en_US |
