Communications Blockset

Error Statistics

The Error Rate Calculation block compares input data from a transmitter with input data from a receiver. It calculates these error statistics:

• Error rate
• Number of error events
• Total number of input events

The block reports these statistics either as final values in the workspace or as running statistics at an output port.

You can use this block either with binary inputs to compute the bit error rate, or with symbol inputs to compute the symbol error rate. You can use frame-based or sample-based data. Also, if you use frame-based data, then you can have the block consider certain samples and ignore others.

The example in the section Example: Soft-Decision Decoding illustrates the use of the Error Rate Calculation block.
