In the mobile communication standard GSM/EDGE, the base station can select one of eight training sequence codes as midamble of the downlink transmitted bursts. If the receiving mobile station uses zero intermediate frequency (IF) sampling the channel estimation is sensitive to the DC offset and IQ gain/phase imbalance of the RF transceiver.
