<p>A radio communication system in which a transmission station performs window function processing on a transmission symbol to which cyclic prefixes have been attached for each specified number of samples, then transmits the signal, and a receiving station extracts and demodulates effective signal portions from the received signal, wherein the transmission station uses a control channel to notify the receiving station of window width N win of the window function; the receiving station adjusts the extraction position of the received signal based on the window width notified from the transmission station; and the receiving station uses the extracted received signal to execute demodulation processing of the transmission symbol. With this system, in an environment in which there are both transmission stations that perform window function processing on a transmission signal and transmission stations that do not perform window function processing, it is possible for the receiving station to effectively use cyclic prefixes CP and to perform demodulation without receiving the effect of distortion caused by the window function processing.</p> |
