This paper deals with a relative calibration approach in terms of non-reciprocal transceivers in a multi-user MISO-OFDM TDD broadcast scenario where linear pre-equalization strategies are applied. The calibrated system, which is achieved by solving a total least squares problem, is compared with robust minimum mean square error pre-equalizer designs. Simulation results including channel estimation errors show a superior behavior of the calibrated system especially with a severe base station… CONTINUE READING
