Abstract:
There is provided a communication method using a human body as a medium. A modulation apparatus using a frequency selective baseband according to an aspect of the invention may include: a serial-to-parallel conversion unit converting serial data supplied from an upper layer into parallel data consisting of M+1 number of data input bits; and a frequency selective spreader selecting one subgroup among a plurality of subgroups obtained by dividing 2N number (where N is a positive integer) of spreading codes used for frequency spreading by 2M (where M is a positive integer, and M
