ABSTRACT:
In the communication system, a transmission signal based on the first radio access scheme is generated, and in the communication system a transmission signal based on the second radio access scheme different from the first radio access scheme is generated. A usage status of the frequency spectrum of the transmission signal based on the first radio access scheme, as well as the known parameters of the transmission signal based on the second radio access scheme, are determined by the pulse-shaping controller. Then, the pulse-shaping controller performs control so as to pulse-shape the transmission signal based on the first radio access scheme by means of the transmit filter on the basis of the result of the above determination, or performs control so as to pulse-shape the transmission signal based on the second radio access scheme by means of the transmit filter on the basis of the result of the above determination.
