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 ...

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 ...

Suppose, the channel is frequency selective or in other words broadband. Therefore, the received signal at moment k in the discrete domain (after sampling) is as follows: Let 𝐿 be the total number of ...

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 ...

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: 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: In optical wireless communications (OWC), hybrid optical orthogonal frequency division multiplexing (O-OFDM) schemes, such as hybrid asymmetrically clipped O-OFDM (HACO-OFDM) and layered ...
