  • Method of decoding a received SC-FDMA symbol in a receiver in a OFDM communication system, a receiver, an apparatus, an OFDM communication system and a computer program product
    Patent number: 9369322
    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: Q i = H i H ? S - 1 ? H i ; Q ^ = 1 N sc ? ? i = 0 N sc - 1 ? Q i ; K ^ = diag ? ( ( Q ^ + C - 1 ) - 1 ? Q ^ ) 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.

  • Channel estimation in wireless communication
    Patent number: 9118515
    Abstract: A channel estimation processor for a receiver in a wireless communication system is described. The channel estimation processor includes a stage-1 processor (STG1) arranged to pluralities of Nsym reference symbol correlation values per slot. The channel estimation processor includes a stage-2 processor (STG2) comprising a plurality of stage-2a processors for obtaining filtered outputs per slot, a respective plurality of stage-2b processors for obtaining respective slot filter results and a stage-2 adder (STG2ADD) for obtaining channel estimates for respective anchor positions. The stage-2a processors are arranged to filter respective pluralities of reference symbol correlation values using respective reference symbol filters (ga) to obtain a respective filtered output per slot.
