Communication signal noise component determining method, involves finding hue of estimated noise based on center of gravity of correlation sequence and passing it through filter when hue is greater than predetermined level

摘要

The method involves receiving a signal having a noise and estimating the amount of the noise in the signal. The hue of the estimated amount of noise is determined based on the center of gravity of the noise correlation sequence by signal processing unit. The received signal is passed through a whitening filter (80) when the hue of the noise is greater than a predetermined threshold level. Independent claims are also included for the following: (a) a communication apparatus (b) a computer program product directly loadable into an internal memory associated with a processor.
