For the uplink transmission of an OFDMA system, frequency synchronization is particularly
challenging due to the presence of multiple Carrier Frequency Offsets (CFOs). This problem …

Coherent detection of transmitted signals in wireless communication systems necessitates
the need for accurate estimation of Channel State Information (CSI) at the receiver. This is …
