  • Dataflow Modeling and Design for Cognitive Radio Networks 

    Wang, Lai-Huei; Bhattacharyya, Shuvra S.; Vosoughi, Aida; Cavallaro, Joseph R.; Juntti, Markku; Boutellier, Jani; Silven, Olli; Valkama, Mikko (2013-10-01)
    Cognitive radio networks present challenges at many levels of design including configuration, control, and crosslayer optimization. In this paper, we focus primarily on dataflow representations to enable flexibility and ...
  • Highly Scalable On-the-Fly Interleaved Address Generation for UMTS/HSPA+ Parallel Turbo Decoder 

    Vosoughi, Aida; Wang, Guohui; Shen, Hao; Cavallaro, Joseph R.; Guo, Yuanbin (2013-06-01)
    High throughput parallel interleaver design is a major challenge in designing parallel turbo decoders that conform to high data rate requirements of advanced standards such as HSPA+. The hardware complexity of the HSPA+ ...
  • Decision-Directed Channel Estimation Implementation for Spectral Efficiency Improvement in Mobile MIMO-OFDM 

    Ketonen, Johanna; Juntti, Markku; Ylioinas, Jari; Cavallaro, Joseph R. (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 ...
  • GPU-based Acceleration of Symbol Timng Recovery 

    Kim, Scott C.; Plishker, William L.; Bhattacharyya, Shurva S.; Cavallaro, Joseph R. (2012-12-20)
    This paper presents a novel implementation of graphics processing unit (GPU) based symbol timing recovery using polyphase interpolators to detect symbol timing error. Symbol timing recovery is a compute intensive procedure ...
  • 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 ...
