Embodiment Construction

[0066] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0067] First of all, the application scenario of the present disclosure is described. In a communication system, it is usually necessary to estimate the power of the signal when calculating RSSI (Received Signal Strength Indication, received signal strength indication) and calculating noise power. In related technologies, you can by formula Estimate the power of the signal, where |a n |Represents the modulus value of the nth sampling point of the signal, N represents the number of sampling points of the signal, p represents the estimated power value of the signal, as can be seen from the above formula, it is necessary to calculate the power for each samplin...

Abstract

The disclosure relates to a method and device for obtaining a power estimation value, a storage medium and electronic equipment. The method for obtaining the power estimation value comprises the following steps: obtaining the absolute value corresponding to each sampling point of a target signal; obtaining a first average value of the absolute values; confirming the standard deviation of the target signal according to the first average value; and obtaining the power estimation value of the target signal according to the standard deviation. Thus, the algorithm for obtaining the power estimationvalue of the target signal is optimized; and calculating the power of each sampling point separately in the prior art is avoided; therefore, the multiplication is reduced, the consumption of system resources is reduced, and the efficiency of obtaining the power estimation value is improved.

Description

technical field [0001] The present disclosure relates to the technical field of signal processing, and in particular, to a method, device, storage medium, and electronic device for obtaining an estimated power value. Background technique [0002] Power estimation is applied in the field of communication and signal processing. In related technologies, the power can be calculated for each sampling point of the signal, and then the average value of each power value can be obtained to obtain the power estimation value of the signal. [0003] In the process of realizing the present invention, the inventor found that the above method has at least the following defects: in the process of calculating the estimated power value, it is necessary to calculate the power for each sampling point separately, so there are more multiplication operations, thus consuming more system resources, resulting in low efficiency in obtaining the power estimate. Contents of the invention [0004] In ...
