Abstract

A simple and applied method for blind SNR estimation in wireless communication signals is presented. Corner is an important information parameter in power distribution function, Signal bandwidth and signal-noise-ratio (SNR) can be accurately estimated through testing the parameter. Theoretical analysis and simulation show that the new algorithm doesn´t need any prior information, has lower computational complexity and higher precision, suitable for hardware implementation.
