摘要:
A human body communication system is disclosed, which includes a plurality of intra-body communication apparatuses, a plurality of extra-body communication apparatuses, a bridge apparatus, and an access point. The bridge apparatus manages connections between the intra-body communication apparatuses and the extra-body communication apparatuses, and performs packet exchange. The access point performs packet exchange between a plurality of bridge apparatuses. The bridge apparatus performs negotiation with communication apparatuses to set up a connection, and manages a path based on the connection setup.

A transmitter using a method of block code-based group modulation includes a grouping unit, a generating unit, and a mapping unit. The grouping unit generates symbols by grouping a data bit stream into N-bit groups, and the generating unit generates a codeword set composed of codewords corresponding to combinations of arrangements of pulses that are generated by a result of grouping to a predetermined number. Next, the mapping unit block-maps a codeword selected from the codeword set to groups constituting the symbols.
