  • High-Throughput Multi-rate LDPC Decoder based on Architecture-Oriented Parity-Check Matrices 

    Radosavljevic, Predrag; de Baynast, Alexandre; Karkooti, Marjan; Cavallaro, Joseph R. (2006-02-01)
    High throughput pipelined LDPC decoder that supports multiple code rates and codeword sizes is proposed. In order to increase memory throughput, irregular block structured parity-check matrices are designed with the ...
  • Implementation Trade-Offs For Linear Detection In Large-Scale MIMO Systems 

    Yin, Bei; Wu, Michael; Studer, Christoph; Cavallaro, Joseph R.; Dick, Chris (IEEE, 2013-06)
    In this paper, we analyze the VLSI implementation tradeoffs for linear data detection in the uplink of large-scale multiple-input multiple-output (MIMO) wireless systems. Specifically, we analyze the error incurred by ...
  • Semi-Parallel Architectures For Real-time LDPC Coding 

    Karkooti, Marjan (2004-05-01)
    Error correcting codes (ECC) enable the communication systems to have a low-power, reliable transmission over noisy channels. ow Density Parity Check codes are the best known ECC code that can achieve data rates very close ...
  • Semi-parallel Reconfigurable Architectures for Real-time LDPC Decoding 

    Karkooti, Marjan; Cavallaro, Joseph R. (2004-04-01)
    This paper presents a semi-parallel architecture for decoding Low Density Parity Check (LDPC) codes. A modified version of Min-Sum algorithm has been used which has the advantage of simpler computations compared to Sum-Product ...
  • Transceiver Design for Efficient Channel Estimation in MIMO OFDM Systems 

    Lou, Feifei (2005-12-01)
    In this thesis, we first compare the least squares (LS) channel estimation performance in terms of mean squared error (MSE) with the perfect knowledge of channel length $L$ versus the estimation without the knowledge ...
