Noise immunity of QAM-OFDM signal reception using soft-decision demodulation in the presence of narrowband interference

Noise immunity of QAM-OFDM signal reception using soft-decision demodulation in the presence of narrowband interference

Objectives. The aim of this paper is to study the noise immunity of digital information transmission in systems with orthogonal frequency division multiplexing (OFDM) and quadrature amplitude modulation (QAM) of subcarriers in the presence of narrowband interference. As a way of managing this interf...
