As an example, assume this transmitted bit sequence: 1 1 0 0 0 1 0 1 1 and the following received bit sequence: 0 1 0 1 0 1 0 0 1, The numbe. The packet error ratio (PER) is the number of incorrectly received divided by the total number of received packets. A packet is declared incorrect if at least one bit is erroneous. The expectation value of the PER is.

In, the number of bit errors is the number of received of a over a that have been altered due to,, or errors. The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. Bit er.
