WebOrthogonal frequency division multiplexing (OFDM) is a modulation technique that is used in several applications ranging from cellular systems (3GLTE, WiMAX), wireless local area networks (LANs), digital audio radio, underwater communications, and even optical light modulation. OFDM combines several signals operating at different frequencies ... WebOrthogonal frequency division multiplexing (OFDM) allows high-speed data transmission across a dispersive channel, so is used in many new and emerging high-speed wired and wireless communication systems. However, OFDM is not used in commercial optical communication systems [1]. This is because OFDM signals are bipolar, while in optical ...

The OFDM … WebIt is the smallest unit of the resource grid made up of one subcarrier in frequency domain and one OFDM symbol in time domain. Resource Element Group (REG) : One REG is …
WebOrthogonal frequency-division multiplexing (OFDM) is a method of digital signal modulation in which a single data stream is split across several separate narrowband channels at different frequencies to reduce interference and crosstalk . The original data stream bits -- that in a conventional single-channel modulation scheme would be sent ... WebEfficient removal of impulsive noise (IN) from received signal is essential in many communication applications. In this paper, we propose a two stage IN mitigation approach for orthogonal frequency-division multiplexing (OFDM)-based communication systems. In the first stage, a deep neural network (DNN) is used to detect the instances of …
