摘要: For the application of advanced smart antenna and MIMO techniques as joint transmission, channel inversion Tomlinson-Harashima pre-coding in future radio systems, side information is required at transmitter. In time-division duplex mode, reciprocal coefficients estimated uplink may principle be reused downlink. practice, reciprocity must not limited to frequency between antennas but it should available also transceiver interfaces baseband signal processing. Here we propose a new design suitable for these techniques.
