Claim 7:
8. A method for transmitting a vector of information symbols over an optical fiber transmission channel made of a multi-core fiber, optical signals carrying said vector of information symbols propagating along the multi-core fiber according to two or more cores, wherein the method comprises:
determining a precoding matrix depending on one or more fiber parameters associated with said multi-core fiber and precoding said vector of information symbols by multiplying the vector of information symbols by said precoding matrix; and
determining a core loss value associated with each of said two or more cores depending on fiber parameters and at least one misalignment loss value, each core loss value being a random variable of a lognormal distribution defined by a mean value and a variance value, said mean value and variance value being dependent on the fiber parameters and the at least one misalignment loss value.
