Bit error rate of two bit sequences of the same length.

Parameters:

• rx_bits (array_like) – the decided bits.

• tx_bits (array_like) – the transmitted bits.

Returns:

the fraction of different bits.

Return type:

float

Raises:

ValueError – for sequences of different lengths.

Examples

>>> import comnum
>>> comnum.ber([0, 1, 1, 0], [0, 1, 0, 0])
