Radio Frequency Identification (RFID) technology, which identifies target and obtains relevant information with non-contact, two-way data communication by radio frequency signal through space coupling. Because of a long communication distance of the Ultrahigh Frequency (UHF) Radio Frequency Identification system, there are several problems:channel attenuation, signal multipath interference and anti-collision of multi-tagscommunication etc. Therefor the reliability

Radio Data Systems was development started20years ago in the European Broadcast Union, EBU, it is a new technology which takes advantage of the spare frequency spectrum resources of the FM radio to achieve extending business. The developers aimed to ease the process of tuning in to a station, especially as the number of broadcasters was

CRC (Cyclic Redundancy Check) is one kind of short cyclic code, which is used to detect errors in the area of data communication and compression. It is a kind of special linear block code, and is widely used in the data transmission networks. The coding and decoding of CRC can be implemented by a linear

As we all know, in cold winter, especially in north area, the temperature of outdoor is 10 Celsius scales under zero even reach dozens Celsius scale under zero. However many people’s car will place out of the door just because they have no carport. To startup the cars in this temperature is not only difficult
