The block diagram refers to the typical OFDM modulation, where the initial data is assumed to be in the frequency domain. The process can be broken down as follows: Data Input: A large serial data ...

This paper proposes a next-generation physical layer technique to realize a more spectrally efficient FD-IM called SBIM-OFDM (single block index modulation-OFDM). All SBIM-OFDM subcarriers are active ...

This project delved into OFDM signal transmission and reception using MATLAB. It examined the influence of SNR on BER, considered multipath fading effects, and compared BPSK and QPSK modulation. OFDM ...

OFDM is a complex form of modulation that combines QAM and frequency-division multiplexing (FDM), the latter being the method by which different signals can simultaneously occupy a frequency band by ...
