Problems solved by technology

[0004] The emergence of environmental backscatter communication technology has a great impact on the continuous communication between sensor nodes, and the information transmission through the load adjustment of the antenna can effectively reduce the system energy consumption; but despite this, the low transmission rate of environmental backscatter communication (several Ten kbps) and short communication distances limit the communication performance and application between sensor nodes, and require a higher signal-to-noise ratio (SNR) to compensate for the bit error rate (BER) generated during communication; therefore, on this basis Designing a new signal transmission system is of great significance to the development of mutual communication between wireless communication devices
