The invention relates to a symbol timing synchronization system for orthogonal frequency division multiplexing system. According to the invention, the symbol timing synchronization system utilizes a shift register and a comparing device to determine whether the symbol of the orthogonal frequency division multiplexing system has the inter-symbol interference. When the symbol has the inter-symbol interference, a compensator is utilized to compensate the interfered symbol. Therefore, depending on the symbol timing synchronization system of the invention, the symbol timing error and the inter-symbol interference can be essentially removed so as to improve the system performance.

A temperature tracking and monitoring system used for commodities transportation comprises a deliver unit, a control computer and a monitor and control unit. The deliver unit comprises a transportation means, at least a glove compartment, a RFID tag and a RFID reader. The glove compartment is disposed in the transportation device the RFID tag is disposed in the glove compartment and has provision for transmitting an identification code. The control computer is adapted to communicate with the RFID reader to receive a temperature signal and the identification code. The control computer transmits a positioning request signal, receives real-time position data, transforms the real-time position data into a position signal and transmitting the position signal, the temperature signal and the identification code in a specific manner. The monitor and control portion comprises a positioning device and a logistics center. The positioning device transmits the real-time position data to the control computer in response to the positioning request signal. The logistics center receives the position signal, the temperature signal and the identification code so as to acquire information of a position and a temperature of the glove compartment reading content of a local message.
