An original modulation technique has been recently proposed for wireless communication systems known as OFDM- SPM (OFDM with Subcarrier Power Modulation). This technique utilizes a characteristic of ...
We conducted Monte Carlo simulations to compare the performance of both OFDM and OCDM-based systems through bit-error-rate (BER) against signal-to-noise ratio (Eb/No), considering different values of ...
Fig. 1 GFDM-based 5G transceiver block diagram: (a) Transmitter; (b) Receiver. The GFDM waveform is the core of the 5G transceiver. The innovative modulation scheme uses a non-orthogonal waveform that ...
Figure 5 shows a basic block diagram of a complete end-to-end OFDM system consisting of a transmitter and receiver. The bit stream enters the system on the left of the diagram. As typical, this single ...
Figure 1. A comprehensive block diagram of OFDM system. path [17] . At the receiving end, signal is converted from serial to parallel in order to separate each subcarrier, then the cyclic prefix of ...
This work will be structured as following: in Section 2, the theory of the OFDM system is presented. Block diagrams, mathematical relations and some OFDM design parameters are stated. In Section 3, ...
