5G PDSCH: performance analysis of DMRS and PTRS designs for channel and phase noise estimation in MM-WAVE
(Bilkent University, 2021-08)The mm-Wave is one of the main enablers for the performance requirements of 5G. Although it provides communication systems with huge bandwidth and data rates, it also has some disadvantages as the carrier frequencies can ... -
Fair user scheduling for downlink power domain NOMA
(Bilkent University, 2019-06)Non-Orthogonal Multiple Access (NOMA) has been proposed as a new radio access technique in which multiple users (the case of user pairs or triples are covered in this thesis) are allowed to use the wireless channel ... -
High-power and low-loss SPDT switch design using gate-optimized GaN on SiC HEMTs for S-band 5G T/R modules
(Bilkent University, 2022-07)Radio frequency (RF) switches are one the fundamental components of modern communication systems. They enable the routing of high-frequency signals into different transmission paths. Therefore, they play a crucial role in ... -
Performance of edge windowing for OFDM under non-linear power amplifier effects
(IEEE, 2017)Edge windowing is a windowing technique for Orthogonal Frequency Division Multiplexing (OFDM) signals based on the idea of using shorter cyclic prefix (CP) and longer window lengths at the edge subcarriers while keeping ... -
Zone based GLRT for detecting physical random access channel signals in 5G
(Bilkent University, 2019-12)In LTE/5G systems, the random access channel (RACH) process occurs during the boot-up phase. As channel state information is not available at this stage, detecting several devices with high performance presents a challenging ...
