Embodiment 1
[0078] This embodiment discloses an ultrasonic communication method in the human body based on group index modulation, such as figure 1 As shown, the steps are as follows:
[0079] S1. On the sending node, perform serial / parallel conversion on the serial information, and divide it into multiple information blocks, each information block includes Y modulation bits and M index bits. In this embodiment, every 5 bits is an information block, wherein the first 3 bits are modulation bits, and the last 2 bits are index bits.
[0080] In this embodiment, the sending node may be, for example, a medical device implanted in a human body, or a wearable sensing device. The sending node is located in a wireless communication network using the human body as a transmission medium, and the number of sending nodes can be set to one or more. The wireless communication network also has a receiving node. The receiving node can be, for example, a medical device implanted in the human body, or a w...
Embodiment 2
[0137] This embodiment discloses an ultrasonic communication device in the human body based on group index modulation, such as image 3 As shown, it includes: a transmitter module and a receiver module. The transmitter module is wirelessly connected to the receiver module through the human body. The transmitter module and the receiver module can be, for example, medical devices implanted in the human body, or wearable sensing devices. .
[0138] Wherein, the sending end module includes a first converter, a packet module, an index modulator, a digital modulator, a second converter and a first communication module:
[0139] The first converter is used to perform serial / parallel conversion on the serial information, divide it into a plurality of information blocks, and transmit the information blocks in parallel to the index modulator and the digital modulator, wherein each information block includes Y modulation bits and M index bits.
[0140] The grouping module is used to di...
