Abstract
In a decoder, the BER is calculated during a decode operation of the decoder. Access to decoder components for obtaining signal data for use in calculating the BER is provided during the decode operation when the components are not used by the decoder. An HDA early termination signal is used to confirm an accurate BER calculation.
Claims20
A decoder comprising:
- a decoding device for decoding an input signal;
- and
- a data error calculator for calculating a data error of the input signal during the decoding of the input signal by the decoder.
A method of determining a data error, the method comprising:
- calculating the data error for an input signal during a decoding process.
A bit error rate (BER) calculation device for use with a decoder, the BER calculation device comprising:
- an encoding component for encoding data from the decoder;
- and
- a BER calculation component configured to calculate a BER using a re-encoding and compare process that is completed at least as early as a decode operation performed by the decoder.
