Error Performance of Burst-Mode Receivers

This paper reports a mathematical model for the evaluation of the bit error rate (BER) performance of burst-mode receivers by taking the effect of random noise and charging/discharging parameters of the receiver into consideration. The distribution of the threshold voltages will be similar to that of the distribution of the values corresponding to logical 1´s of the preamble for threshold setting. The threshold setting will also vary when a long string of consecutive 0´s arrive in the incoming data that report errors in detection. The average threshold is determined for a particular bit position in the consecutive string of 0´s. The expression based on the threshold is also used to determine the BER of the receiver.
