Abstract
Transmitter leakage has a significant impact on the system performance in mobile devices using zero-IF receivers. In contrast to analog approaches, digital Tx leakage compensation approaches can easily be reconfigured and therefore are highly attractive for future mobile devices, using software defined radios. In this contribution we present a digital Tx leakage estimation and compensation approach, using specifically designed OFDM preambles, which are also suitable for the uplink channel estimation.
