Explore MATLAB source code curated for "信噪比估计算法" with clean implementations, documentation, and examples.
This code implements a classic SNR estimation algorithm based on statistical moment estimation principles, utilizing the 2nd and 4th order moments of signals to estimate the signal-to-noise ratio of received signals. The implementation demonstrates how statistical moments can be efficiently calculated for digital signal processing applications.
This algorithm is a classic signal-to-noise ratio estimation method known as the Error Vector Magnitude approach. By calculating the second and fourth-order moments of the in-phase and quadrature components of received signals, the algorithm effectively estimates SNR while offering computational efficiency suitable for real-time implementation through moment-based calculations.
