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 ...
Abstract: In this paper, to reduce the memory size of IFFT for OFDM systems, we propose a new IFFT design based on a mapping of three IFFT input signals: modulated data, pilot and null signals. To ...
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: In this paper, we design and evaluate the wavelet-OFDM (wavelet orthogonal frequency division multiplexing) system based on wavelet transform. Wavelet transform has functions other than the ...
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: One of the limitations of using OFDM technique is its higher PAPR in the time domain signal. The higher PAPR OFDM signal would cause the fatal degradation of BER performance and undesirable ...
