Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device, electronic equipment, and storage medium for estimating a signal-to-noise ratio. Background technique [0002] Spread spectrum is a communication technology that disperses the spectrum of the transmitted signal to be wider than its original bandwidth. Spread spectrum communication is often used in military communication or Internet of Things communication. In military communication systems or Internet of Things communication systems, it is necessary to select and schedule base stations according to the signal strength of spread spectrum. Usually, the signal strength is represented by a Signal-to-Noise Ratio (SNR) value, that is, in a military communication system or an Internet of Things communication system, it is necessary to estimate the SNR value, and select and schedule base stations according to the SNR value.
