    • Advanced packet scheduling for efficient video support with limited channel feedback on MIMO LTE downlink 

      Nonchev, Stanislav; Valkama, Mikko; Hamila, Ridha ( IEEE , 2011 , Conference Paper)
      Next-generation mobile networks will provide users with high data rates, increased mobility and various services. The initial step made in LTE and LTE-A is adopting the OFDM(A) air interface and utilization of dynamic ...

    • Effect of high-velocity scenarios on the performance of MIMO LTE packet scheduling 

      Nonchev, Stanislav; Valkama, Mikko; Hamila, Ridha ( IEEE , 2011 , Conference Paper)
      In this paper we analyze the performance of advanced OFDM packet scheduling techniques based on 3GPP UTRAN Long Term Evolution (LTE) framework for high velocity scenarios. Based on our previous investigations in system ...

    • Phase noise mitigation in OFDMA uplink 

      Samara, Lutfi; Syrjala, Ville; Hamila, Ridha; Valkama, Mikko ( IEEE , 2014 , Conference Paper)
      This paper addresses the problem of the phase noise induced spectral spread in an OFDMA uplink scenario. Accompanied with power differences between the users at the receiver in a multiuser case, the phase noise induced ...
