Systems and methods for creating and using a first and second group of training sequences in a training-aided single-carrier frequency domain equalization system. The first group of training sequences are conventional training sequences and the second group of training sequences are 90&#xb0;-rotated versions of the first group of training sequences.

Training sequences with enhanced IQ imbalance tolerances for training-aided frequency domain equalization

An apparatus comprising a receiver configured to receive a super-symbol comprising a first modulation symbol and a second modulation symbol, wherein the first modulation symbol comprises a first modulation format, and wherein the second modulation symbol comprises a second modulation format, and a processor coupled to the receiver and configured to select, for the first modulation symbol, a first nearest candidate symbol from a first set of candidate symbols associated with the first modulation format, select, for the second modulation symbol, a second nearest candidate symbol independent of the first nearest candidate symbol from a second set of candidate symbols associated with the second modulation format, and determine a soft decision value for a first hit in the super-symbol according to the first nearest candidate symbol and the second nearest candidate symbol.
