Determination of the optimum guard interval for an MC-CDMA system using measurement-based channel models
Frequency selective channel distortions in the Multi Carrier Code Division Multiple Access (MC-CDMA) system is reduced with the use of guard interval. In previous works, guard interval is associated with root mean square ... -
Investigating the effect of movement speed and pilot symbol period on OFDM system performance
Engiz B.K.; Kurnaz Ç.; Sezgin H. (2012)In this study, the effect of time selectivity and pilot symbol period on the performance of an OFDM system with block type based channel estimator was investigated. Performance degradation due to pilot symbol usage was ... -
Investigating the effect of pilot bit arragement on OFDM system performance
Engiz B.K.; Kurnaz Ç.; Sezgin H.; Gökalp H. (2011)In this study, the effect of pilot bit placement on the performance of an OFDM system with comb-type based channel estimator was investigated. Computer simulations were used for this purpose. Least sequares algorithm is ... -
A novel empirical SIR-to-CQI mapping rule for DC-HSDPA systems
Kurnaz Ç.; Korunur Engiz B.; Esenalp M.O. (Turkiye Klinikleri Journal of Medical Sciences, 2017)This study aims to determine the mapping rule for signal-to-interference ratio (SIR) to channel quality indicator (CQI) based on DC-HSDPA real field measurements. The measurements were performed using the TEMS Investigation ... -
Performance analysis of pilot arrangement for OFDM systems over time varying frequency selective channels
Engiz B.K.; Kurnaz Ç.; Sezgin H. (2012)In this study, the effect of pilot arrangement on OFDM system performance for different time and frequency selective fading channels is investigated. Pilot symbols are placed in rectangular 2-D pilot pattern in chosen ... -
Performance evaluation of ANN based channel interpolation for OFDM system
Engiz B.K.; Kurnaz Ç.; Kayhan G. (2012)In this study, the effect of three different techniques that used for interpolation on OFDM system with pilot based comb type channel estimation is investigated and results are given in terms of BER (Bit Error Rate). The ...
