- Signal-noise ratio is an important parameter in modern wireless communication systems and an important indicator to reflect signal quality. An accuracy signal-noise ratio can provide signal quality information required for power control and channel decoder, etc. This paper proposes a blind signal-noise ratio estimation algorithm, which makes use of singular value decomposition of signal autocorrelation matrix to estimate the signal-noise ratio. The algorithm does not require prior information related to the signal and has no special equipments on signal sampling rate and signal type. It is relatively easier, with a certain acceptable complexity to some estimated accuracy extent.
