摘要： 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.

摘要： A communication system capable of achieving a high usage efficiency of frequencies without the need for cooperation of multiplexed users is disclosed. The communication system communicates over frequency channels set by dividing a frequency bandwidth assigned to the system and allows interference between channels by overlapping the adjacent frequency channels with each other in the frequency domain. A transmitting and receiving device, which transmits and receives a signal by allowing the interference between symbols at a waveform level for each channel to decrease the occupied bandwidth, is provided. The receiving device is provided with an Inter-Channel Interference (ICI) removal and Inter-Symbol Interference (ISI) compensation filter serving as either an ICI removal filter for removing the interference between channels or an ISI compensation filter for compensating the interference between symbols.

摘要： To provide a radio communication control apparatus and a radio communication control method capable of controlling simultaneous transmission and reception so as not to degrade system throughput.A simultaneous transmission and reception controller 106 determines whether the simultaneous transmission and reception using the same frequency are possible, based on radio spectrum environment information of an opposite party of communication and radio spectrum environment information of a self-apparatus. When the simultaneous transmission and reception using the same frequency are determined to be possible, a control signal transmission section 109 transmits instruction information, indicating that the simultaneous transmission and reception are possible, and a transmission parameter thereof, to the above communication terminal. After the transmission parameter is set, a communication section 111 executes simultaneous transmission and reception with the above communication terminal using the same frequency, when the simultaneous transmission and reception using the same frequency are determined to be possible.
