Title: Human body communication method using multi-carrier modulation
Inventor: HYOUNG CHANG HEE
IPC: H04L27/26
Filed: 2006-11-03
Abstract: A human body communication method using a multi-carrier modulation scheme is provided to reduce interference between users by using a limited frequency band and to increase the utilization of frequencies by using QPSK(Quadrature Phase Shift Keying) or QAM(Quadrature Amplitude Modulation) within the limited frequency band instead of transmitting high-speed digital signals. A control part judges whether a channel is usable(S710). The control part forms a plurality of subchannels having a certain bandwidth(S720). The control part confirms whether interference signals, received from peripheral devices, exist within the bandwidth of the subchannels(S730). The control part determines a modulation scheme for the subchannels according to the existence or nonexistence of interference signals(S740). Based on the determined modulation scheme, the control part maps data onto symbol data(S750). The control part loads a subcarrier with the symbol data.
