Bit signal-to-noise ratio and bit error rate

In or, (energy per bit to noise power spectral density ratio) is a normalized (SNR) measure, also known as the "SNR per bit". It is especially useful when comparing the (BER) performance of different digital schemes without taking bandwidth into account. The BER may be evaluated using stochastic () computer simulations. If a simple transmission and model is assumed, the BER may also be calculated analytically. An example of such a data source model is the source. Examples of simple channel models used in are:.
