ABSTRACT:
The present invention discloses a burst detection apparatus and method. The burst detection apparatus of the present invention comprises a power module, a soft-metric RMS module, and a quality determination module. The bust detection method comprises the following steps: At first, a reciprocal value of the received signal's power is calculated. Next, a RMS value of the soft-metrics according to the received signal is computed. At last, a product of the reciprocal value and the RMS value is compared with a given threshold value to generate a Boolean outcome as a quality determination decision. If the product of these values is lower than the given threshold value, it means the received signal is believed as noise; otherwise, it is believed as the real signal.
