Abstract
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.
