Abstract:
This invention provides colored noise detection algorithm(s). This colored noise detection algorithm(s) may be implemented with a multi-branch equalizer processing module that enables interference cancellation when colored noise is associated with received radio frequency (RF) bursts. The noise discriminator identifies when the radio frequency (RF) bursts have white noise or colored noise associated with them. Alternatively the noise discriminator may be able to determine and enable interference cancellation in response to an interference-limited received RF burst as opposed to a noise-limited received RF burst. The multi-branch equalizer improves the signal-to-noise ratio by improving the equalization with a second branch operable to be trained based upon known training sequences and at least partially re-encoded data bits.
