| Résumé : | Time reversal (TR) recently emerged as an interestingcommunication technology capable of providing a goodspatio-temporal signal focusing effect. New generations of largebandwidthdevices with reduced cost leverage the use of TRwideband communication systems. TR can easily be integratedinto an orthogonal frequency-division multiplexing (OFDM) systemby precoding the signal in the frequency domain. In thispaper, we first extend the frequency-domain TR precoding to rateback-off factors (BOFs) different than one. We secondly derive aclosed-form mean-square-error (MSE) expression of the receivedequalized symbols as a function of the BOFs and the numberof antennas. The derived MSE formula is validated numericallywith Rayleigh fading channels. |
