Abstract

Some communication systems can be represented with a Hammerstein model; that is the case of the radio over fiber downlink channel. In order to recover the input signal from the received signal, we propose a semi-blind approach based on an input precoding inducing redundancy. The suggested approach makes it possible to jointly estimate the channel and the input sequence. The channel is estimated using a pilot sequence then the symbols are estimated by solving a triangular system of polynomial equations or by calculating the inverse of a given polynomial.
