For future wireless communication technologies, an increase in capabilities
such as throughput is strongly expected. Transmission in the sub-THz bands (>90
GHz) seems to be the potential solution to meet the ever-increasing capacity
demands due to the large unexploited bandwidth. Oscillators used at these
frequencies generate phase noise that induces critical distortions in the
signal that must be addressed. The correlated nature of PN makes it difficult
to overcome. Nowadays, there is a growing interest in considering the extension
of multicarrier based waveforms of the 5G new radio for transmissions in the
sub-THz bands. In this paper, we introduce a new algorithm called the
interpolation filter (IF), which efficiently estimates and compensates PN
effects on DFT-s-OFDM systems. Specifically, it is based on the use of
stochastic properties of the PN and is compatible with the 3GPP phase tracking
reference signal scheme. We highlight a performance improvement over known
techniques when using high-order modulation.Comment: Paper accepted and will be presented at the IEEE CCNC 2023 Conference
