Abstract
A method for estimating transceiver non-idealities is disclosed. In one aspect, the method comprises generating a preamble comprising multiple sets of known training sequences with a synchronization part preceding an estimation part. The training sequences in the estimation part comprises at least two sequences which are (i) complementary Golay sequence pairs and (ii) selected to satisfy a predetermined correlation relationship chosen for estimation of a first non-ideality characteristic. A first estimate of a non-ideality characteristic is determined on the basis of the known training sequences of the synchronization part of the received preamble. The estimation part of the received preamble is compensated by this estimate. Another non-ideality characteristic is determined by the compensated estimation part, exploiting the predetermined correlation relationship.
