Spread Spectrum OFDM-IM With Efficient Precoded Matrix and Low Complexity Detector

Spread Spectrum OFDM-IM With Efficient Precoded Matrix and Low Complexity Detector

This paper introduces a novel scheme that employs efficient precoded matrices for index modulation orthogonal frequency division multiplexing namely (EP-OFDM-IM). This technique implements Discrete Fourier Transform (DFT) and Fast Walsh Hadamard Transform (FWHT) precoded matrices for spreading the s...
