This series is excerpted from “Mobile Broadband Multimedia Networks: Techniques, Models and Tools for 4G.” Part two shows how to enhance OFDM with MIMO and other techniques. The many papers noted in ...

Orthogonal frequency-division multiplexing has become the standard modulation format for 5G New Radio. Lean how OFDM works and how it’s used. Orthogonal Frequency Division Multiplexing (OFDM) is an ...

OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

In this paper, a Fast Fourier Transform (FFT) or inverse FFT processor for Fifth-Generation (5G) Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system’s ...

Abstract: Orthogonal frequency division multiplexing (OFDM) has been proposed for use in ultra-wideband (UWB) communication systems. In a UWB-OFDM transceiver, resource efficient FFT/IFFT hardware is ...

End-to-End OFDM PHY-Layer Simulation in Python (QPSK & 16-QAM) — evolving into an RF validation-style test flow (impairments → metrics → PASS/FAIL). OFDM ...

Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation scheme used in modern wireless communication systems. It divides the available spectrum into many closely spaced ...

ABSTRACT: In multi-carrier wireless OFDM communication systems, a major issue is related to high peaks in transmitted signals, resulting in such problems as power inefficiency. In this regard, a ...

Abstract: Peak-to-average power ratio (PAPR) one of the most important issues in orthogonal frequency division multiplexing (OFDM). Iterative clipping and filtering (CF) is a high efficiency technique ...
