We consider signal space diversity based on Complex Rotation Matrices (CRM) known to provide good performance gains over uncorrelated Rayleigh fading channels. OFDM/OFDMA signals based on LTE-A parameters are combined with CRM, spatial multiplexing (MIMO), Turbo or LDPC codes. Both orthogonal and non-orthogonal CRM are analyzed.
