Abstract

An embodiment of the invention discloses a signal processing method and device and a computer readable storage medium. The method comprises at least one of the following steps: a transmitting end receives at least one of a safety level index, safety level parameter information and channel information fed back by a receiving end, determines a transmitted signal parameter, and / or carries out the signal transmission; the sending end sends at least one of the security level index and the security level parameter information to the receiving end to determine a transmitting signal parameter, and / orsends a signal; the transmitting end determines a transmitting signal parameter according to at least one of the security level index, the security level parameter information and the channel information, and / or transmits a signal. According to the method disclosed in the embodiment of the invention, power leakage of a determined transmitting signal is minimized; interference signals are concentrated in an angle area with high signal leakage power, and adjacent cell interference is prevented. Multi-dimensional random interference is transmitted in a signal leakage area to resist multi-eavesdropping, and security threat of multi-eavesdroppers to a wireless system is effectively reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a signal processing method, device and computer-readable storage medium. Background technique [0002] In wireless communication systems, due to the openness and broadcasting of wireless channels, physical layer security has become a weak link in the security maintenance of wireless communication systems. At the same time, most of the traditional security technologies are based on cryptography theory, and there are problems such as low key distribution rate and long system delay when facing a large number of users. With the frequent occurrence of eavesdropping incidents in recent years, how to maintain physical layer security has become an important research direction. [0003] In wireless systems such as LTE (Long Term Evolution, Long Term Evolution) currently in use, base stations are equipped with multiple antennas, and beamforming technology is used in...
