We study the statistics of optical data transmission in a noisy nonlinear fiber channel with a weak dispersion management and zero average dispersion. Applying path integral methods we have found exactly the probability density functions of channel output both for a non-linear noisy channel and for a linear channel with additive and multiplicative noise. We have obtained analytically a lower bo...

We derive a criterion on the measurability / identifiability of Multiple–Input Multiple–Output (MIMO) channels based on the size of the so-called spreading support of its subchannels. Novel MIMO transmission techniques provide high-capacity communication channels in time-varying environments and exact knowledge of the transmission channel operator is of key importance when trying to transmit in...

In this correspondence, we describe the achievable rate region for reliably recovering deterministic functions of correlated sources which have a finite alphabet. The method of proof is almost the same as that used to prove the Slepian-Wolf theorem.
