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 ...

Transmitter Block 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 ...

Existing frequency domain index modulation (FD-IM) schemes for orthogonal frequency division multiplexing (OFDM) are proposed to trade-off between spectral effi ...

PSK is another modulation scheme that maps information symbols onto a transmitted carrier signal. With this scheme, however, the symbols are distributed onto a constellation that forms a circle, i.e., ...
