Sažetak
In this letter, a novel low-complexity modulation for Capacitive Coupled Human Body Communications (CC-HBC) is proposed. Called Inductance Index Modulation (IIM), the proposed method refers to the channel conditions between transmitters and receivers that are used as a new signal space. Precisely, at the transmitter side, one of the M=2n inductances is selected according to the incoming n bits, in order to change the CC-HBC channel condition between transmitters and receivers. Then, at the receiver side, the transmitted bits are predicted by estimating the CC-HBC channel conditions using the maximum (ML) detector. The CC-HBC channel is modeled using the transfer function method. The BER performance of the proposed scheme is compared with conventional modulations, yielding a very promising approach.
