Abstract
A method of decoding a received SC-FDMA symbol in a receiver in a OFDM communication system is described. The method comprises calculating an approximate constellation energy {circumflex over (K)} from channel matrices Hi for all subcarriers i, a noise covariance matrix S, and a data signal power matrix C associated with the OFDM symbol, an approximate constellation energy {circumflex over (K)}. The approximate constellation energy {circumflex over (K)} is calculated according to:The method further comprises decoding the received symbol using at least the associated approximate constellation energy {circumflex over (K)}. Also, a receiver, an apparatus, an OFDM communication system and a computer program product for such decoding are described.
