A multi-carrier OFDM system using a Cyclic Prefix for preventing inter-block interference is known to be equivalent to multiple flat fading parallel transmission channels in the frequency domain. Linear Precoding consists in multiplying by a N x K matrix a K-dimensional vector obtained by serial to parallel conversion of a symbol sequence to be transmitted. In this paper, the performance of MMSE receivers for certain large random isometric precoded OFDM systems on fading channels is analyzed.
