A system and a method for graphical resources management, and a computer program product with an application for graphical resources management are provided, which may capture groups of pixels from imported graphical resources to generate a plurality of graphical items, edit relationships between the graphical items, and generate a graphical data structure that demonstrates the relationships between the graphical items. The invention allows a user to logically manage graphical resources in a structured manner, and thus enables efficient management of graphical resources.

System and method for graphical resources management and computer program product with application for graphical resources management

A signal transmitting method, a signal receiving method, and a signal receiving device are adapted to an OFDM system. In the signal transmitting method and signal receiving method, double asymmetric training symbols are used for performing time-varying channel response estimation. In the transmitting method, asymmetric pilot sub-carriers are added in data sub-carriers to form a plurality of first and second training symbols. The pilot symbols in the first and second training symbols are asymmetrically configured. In the receiving method, a channel response corresponding to each pilot sub-carrier is estimated by using two adjacent asymmetric pilot symbols. The received data sub-carrier is then restored through the channel response. Through the signal transmitting method and signal receiving method, even in a transmitter or a receiver moving at a high speed, more bandwidths can be used to transfer data, and contents of the transferred data can be correctly estimated.
