Carrier frequency offsets problem in recent DST‐SC‐FDMA system: Investigation and compensation
The Journal of Engineering, 2021 Carrier frequency offset (CFO) is a challenging problem in the uplink of the single‐carrier frequency division multiple access (SC‐FDMA) system. CFOs effect on the orthogonality between subcarriers and cause inter‐carrier interference (ICI) and multiple ...

Improved Signal Detection Techniques for QOSTBC System in Fast Fading Channel
Journal of Telecommunications and Information Technology, 2020 Most existing quasi-orthogonal space time block coding (QO-STBC) schemes have been developed relying on the assumption that the channel is flat or remains static during the length of the code word symbol periods to achieve an optimal antenna diversity ...

CLIPPING TECHNIQUES FOR PAPR REDUCTION IN FBMC/OQAM SYSTEM OVER DOUBLY-SELECTIVE CHANNELS
Journal of Engineering and Sustainable Development, 2021 One of the major disadvantages of Filter Bank Multicarrier (FBMC) is high Peak-to-Average Power Ratio (PAPR) of transmitted signal. As a result, nonlinear power amplifier (PA) properties, considerable out-of-band and the in-band distortion types take ...
