Abstract--We introduce a signal processing approach to com-
pensate for the timing jitter produced by the acoustic effect in
soliton communications. The other main sources of timing jitter,
the Gordon­Haus effect and the polarization effect, are inherently
stochastic. By contrast, the acoustic effect is deterministic and
becomes the dominant source of bit error rates in standard
soliton systems when the bit rates are more than 10 Gb/s and the
transmission distance is more than several thousand kilometers.
We exploit the deterministic nature of the acoustic effect to
introduce a scheme that predicts the amount of timing jitter as a
function of the previous transmitted bits and uses the information
to adjust the sampling period of the received soliton pulses. We
demonstrate successful application of the scheme by simulations
and discuss implementation issues.
