The resulting limit, given in units of bits per second, is the absolute maximum rate of error-free communication given signal strength and noise level.

Based on the principle of modulus maximum, a new approach using scalogram of wavelet transform for transient signal, under noise free condition or noise condition separately, is described.

Be free to keep your conversation going while walking down a gusty street because our team of scientists developed a unique Digital Sensor Signal Fusion system to reduce wind noise.
