  • Flexible N-Way MIMO Detector on GPU 

    Wu, Michael; Yin, Bei; Cavallaro, Joseph R. (2012-10-17)
    This paper proposes a flexible Multiple-Input Multiple-Output (MIMO) detector on graphics processing units (GPU). MIMO detection is a key technology in broadband wireless system such as LTE,WiMAX, and 802.11n. Existing ...
  • FPGA Prototyping of A High Data Rate LTE Uplink Baseband Receiver 

    Wang, Guohui; Yin, Bei; Amiri, Kiarash; Sun, Yang; Wu, Michael; Cavallaro, Joseph R. (2009-11-01)
    The Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standard is becoming the appropriate choice to pave the way for the next generation wireless and cellular standards. While the popular OFDM ...
  • High-Level Design Tools for Complex DSP Applications 

    Sun, Yang; Amiri, Kiarash; Wang, Guohui; Yin, Bei; Cavallaro, Joseph R.; Ly, Tai (2012-07-12)
    High-level synthesis design methodology - High level synthesis (HLS) [1], also known as behavioral synthesis and algorithmic synthesis, is a design process in which a high level, functional description of a design is ...
  • Implementation Trade-Offs For Linear Detection In Large-Scale MIMO Systems 

    Yin, Bei; Wu, Michael; Studer, Christoph; Cavallaro, Joseph R.; Dick, Chris (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 ...
  • Low complexity MMSE based interference cancellation for LTE uplink MIMO receiver 

    Yin, Bei; Cavallaro, Joseph R. (2011-12-01)
    In this paper, we propose a novel low complexity minimum mean square error (MMSE) interference cancellation (IC) to minimize the residual inter-symbol and inter-antenna interference in LTE/LTE-Advanced uplink. In the ...
  • Low Complexity Opportunistic Decoder for Network Coding 

    Yin, Bei; Wu, Michael; Wang, Guohui; Cavallaro, Joseph R. (2012-12-01)
    In this paper, we propose a novel opportunistic decoding scheme for network coding decoder which significantly reduces the decoder complexity and increases the throughput. Network coding was proposed to improve the ...
  • LTE uplink MIMO receiver with low complexity interference cancellation 

    Yin, Bei; Cavallaro, Joseph R. (2012-11-01)
    In LTE/LTE-A uplink receiver, frequency domain equalizers (FDE) are adopted to achieve good performance. However, in multi-tap channels, the residual inter-symbol and inter-antenna interference still exist after FDE ...
  • Parallel Nonbinary LDPC Decoding on GPU 

    Wang, Guohui; Shen, Hao; Yin, Bei; Wu, Michael; Sun, Yang; Cavallaro, Joseph R. (2012-12-01)
    Nonbinary Low-Density Parity-Check (LDPC) codes are a class of error-correcting codes constructed over the Galois field GF(q) for q > 2. As extensions of binary LDPC codes, nonbinary LDPC codes can provide better ...
  • Reconfigurable Multi-Standard Uplink MIMO Receiver with Partial Interference Cancellation 

    Yin, Bei; Amiri, Kiarash; Cavallaro, Joseph R.; Guo, Yuanbin (2012-06-01)
    As HSPA/HSPA+ and LTE/LTE-A evolve in parallel, the reconfigurability of a receiver to support multiple standards has become more and more important, especially for small cells. In this paper, we first suggest a reconfigurable ...
