Embodiment Construction

[0089] Such as Figure 1 to Figure 8 As shown, the present invention discloses a power allocation method based on confidentiality probability in a millimeter wave system, including the following steps:

[0090] S1. The equivalent channel modeling step is to establish a millimeter wave channel model and thereby obtain a discrete angle domain channel model;

[0091] S2. The allocation strategy definition step is to impose mandatory constraints on the minimum value of the receiving signal-to-noise ratio in the legal direction, and at the same time limit the upper limit of the receiving signal-to-noise ratio in the eavesdropping direction, formulate a distribution strategy for the total transmission power, and ensure that the target confidentiality probability meets the quality of service requirements. constraint;

[0092] S3. The power allocation step is to perform power allocation based on the interruption-based artificial noise beamforming, and perform performance evaluation o...

Abstract

The invention discloses a method of security probability-based power allocation in a millimeter wave system. The method comprises the following steps: S1, an equivalent channel modeling step, whereina millimeter wave channel model is established, and thus a discrete angular domain channel model is obtained; S2, a power allocation strategy defining step, wherein a minimum value of a receiving signal-to-noise ratio of a legal direction is forcibly restricted, an upper boundary of a receiving signal-to-noise ratio of an eavesdropping direction is limited at the same time an allocation strategy of total transmission power is formulated, and an effect that target security probability meets constraints of quality-of-service demand is guaranteed; and S3, a power allocation step, wherein artificial noise beamforming power allocation based on interruption is carried out, and performance evaluation is carried out on a final allocation result. The invention provides the power allocation method with a data protection function, privacy and confidentiality of data in a wireless communication process can be effectively improved, established security probability is achieved, normalized safety throughput is increased, and system complexity is reduced.

Description

technical field [0001] The present invention relates to a power allocation method, in particular to a power allocation method between useful information and artificial noise in a millimeter wave system combining large-scale antenna array and beamforming technology, which can protect the privacy of target user data sex, disturbing eavesdroppers. It belongs to the field of communication system physical layer security. Background technique [0002] With the continuous improvement of user experience in high-quality data transmission, people's demand for wireless communication data transmission rate and signal bandwidth is increasing day by day. The design of next-generation mobile communication systems is facing the reality of scarce spectrum resources. At the same time, the next generation mobile communication system will pay great attention to channel capacity, system versatility and maintenance cost. In recent years, due to the abundant license-free spectrum resources and t...
