  • Decision-Directed Channel Estimation Implementation for Spectral Efficiency Improvement in Mobile MIMO-OFDM 

    Ketonen, Johanna; Juntti, Markku; Ylioinas, Jari; Cavallaro, Joseph R. (Springer, 2013-09-30)
    Channel estimation algorithms and their implementations for mobile receivers are considered in this paper. The 3GPP long term evolution (LTE) based pilot structure is used as a benchmark in a multiple-input multiple-o ...
  • Implementation of LS, MMSE and SAGE Channel Estimators for Mobile MIMO-OFDM 

    Ketonen, Johanna; Juntti, Markku; Ylioinas, Jari; Cavallaro, Joseph R. (IEEE, 2012-12-01)
    The use of decision directed (DD) channel estimation in a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) downlink receiver is studied in this paper. The 3GPP long term evolution ...
  • Performance - Complexity Comparison of Receivers for a LTE MIMO–OFDM System 

    Ketonen, Johanna; Juntti, Markku; Cavallaro, Joseph R. (IEEE, 2010-06-01)
    Implementation of receivers for spatial multiplexing multiple-input multiple-output (MIMO) orthogonal-frequency-division-multiplexing (OFDM) systems is considered. The linear minimum mean-square error (LMMSE) and the K-best ...
  • Receiver Implementation for MIMO-OFDM with AMC and Precoding 

    Ketonen, Johanna; Juntti, Markku; Cavallaro, Joseph R. (IEEE, 2009-11-01)
    Receivers for horizontally encoded LTE based MIMO-OFDM systems are considered in this paper. Adaptive modulation and coding (AMC) is used as well as precoding. The linear minimum mean square error (LMMSE), successive ...
  • ASIC Implementation Comparison of SIC and LSD Receivers for MIMO-OFDM 

    Ketonen, Johanna; Myllylä, Markus; Juntti, Markku; Cavallaro, Joseph R. (IEEE, 2008-10-01)
    MIMO-OFDM receivers with horizontal encoding are considered in this paper. The successive interference cancellation (SIC) algorithm is compared to the K-best list sphere detector (LSD). A modification to the K-best LSD ...
