  • An adaptive least squares channel estimation based on conjugate gradient approach for multipath fading CDMA systems 
    Rızaner, Ahmet; Ulusoy, Ali Hakan; Amca, Hasan; Hacıoğlu, Kadri (Computers & Electrical Engineering, Elsevier, 2011-11)
    Multiple access interference (MAI) is the main factor affecting the performance of channel estimation techniques for code division multiple access (CDMA) systems. Although, several multi-user channel estimation algorithms ...
  • An Adaptive Near-far Resistant Single-user Channel Estimation Algorithm for Multipath Fading DS-CDMA Systems 
    Rızaner, Ahmet; Amca, Hasan; Hacıoğlu, Kadri; Ulusoy, Ali Hakan; Scherb, Ansgar (İnternational Conference on Wireless and Mobile Communications/Bucharest, Romania., 2006-07)
    Channel estimation techniques for CDMA systems need to combat multiple access interference and near-far effects to improve the estimation performance. Linear single-user MMSE detector has certain advantages with respect ...

  • Performance Analysis of The Path Selective Decorrelating Detector with a Maximum Likelihood Channel Estimator 
    Ulusoy, Ali Hakan; Rızaner, Ahmet; Hacıoğlu, Kadri; Amca, Hasan (European Wireless 2002,( EW2002),/ Florence-Italy, 2002-02)
    The adaptive path selective decorrelating detector requires the knowledge of the channel coefficients for path selection to reduce both system complexity and noise enhancement. Generally, the channel coefficients are ...
  • Signature Waveform Estimation By Using Short Training Sequences 
    Rızaner, Ahmet; Hacıoğlu, Kadri; Amca, Hasan; Ulusoy, Ali Hakan (International Conference on Information, Communications and Signal Processing (ICIC2001),/Singapore, 2001-10)
    Multiuser detection techniques are known to be effective strategies to counter the presence of multiuser interference in code division multiple access channels. Generally, multiuser detectors can provide excellent performance ...
