<p><P>PROBLEM TO BE SOLVED: To effectively compensate a transmission signal of a terminal device having no function for receiving the transmission signal of the terminal device through a relay, in a transmission system in which signals are transmitted through the relay. <P>SOLUTION: A terminal transmitter 2 and base station transmitter 6 perform transmission to a base station receiver 7 through a relay. Small capacity communication devices 3 and 8 communicate through a communication path differing from that of communication of the terminal transmitter 2. An error detection part 25 detects a signal error by comparing a signal which is transmitted from the base station transmitter 6 and received by the base station receiver 7 with a reference reception signal. A compensation value generation part 26 generates a compensation value for compensating a signal to be transmitted to make a signal to be received by the base station receiver 7 be within an allowable range of the reference reception signal. The small capacity communication device 8 transmits the compensation value generated by the compensation value generation part 26 to the small capacity communication device 3 through a communication path differing from that of communication of the base station transmitter 6. A waveform equalization part 12 compensates a signal to be transmitted by the terminal transmitter 2 on the basis of the received compensation value, when having received the compensation value from the base station device 5. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
