<p>The present invention relates to a method and device for estimating the signal-to-interference-and-noise ratio of a wireless communication system, wherein the method includes: receiving a baseband signal y (S110), and calculating the signal-to-interference-and-noise ratio (S120) according to the baseband signal y. The method and device provided by the present invention has low calculation complexity, and can significantly improve the accuracy of estimation of the signal-to-interference-and-noise ratio, which plays an important role in improving the demodulation performance, providing accuracy in power control, increasing the data transfer rate and achieving a better dynamic allocation of channels.</p> |
