<p>PROBLEM TO BE SOLVED: To provide a communication terminal more suitable than the conventional one.SOLUTION: A communication device inputs a PAM signal that is generated by encoding a transmission object data by the PAM 5 scheme into a digital/analog converter 55 after applying pulse shaping to the PAM signal by a pulse shaping filter 51. A transfer function G(z) of the pulse shaping filter 51 is set to G1(z)=0.667+0.333zapproximating to G0(z)=(2/3)+(1/3)z.</p> |
