ARTIFICIAL INTERFERENCE INSERTION METHODS IN ANALOG-LOW RESOLUTION CONVERSION SYSTEMS

Abstract

The invention relates to the field of wireless communication, and specifically to a method of artificial interference insertion combined with beamforming techniques in a low-resolution analog-to-digital converter (ADC) communication system for the purpose of securing information for the desired receiving device with the following steps: A, At the transmitting device: inserting a CRC from the binary data bit stream; encoding to optimize data transmission over noisy channels; modulating to ensure that data can be transmitted efficiently, accurately, and resource-saving; generating random interference to prevent decoding by eavesdropping devices; beamforming to maximize the SINR of the receiving device and minimize the SINR of the eavesdropping device; mixing the signal with a carrier wave to transmit the signal to the antennas, and transmitting it into the environment to the receiving device.B. At the receiver: convert the received signal from the carrier frequency down to the base frequency; equalize and demodulate to recover the signal; perform low-resolution ADC conversion to save energy and cost; decode and separate the CRC to recover the original data bit stream, estimate the transmission channel, and provide CSI feedback via a dedicated channel.
