Here, the authors are proposing the FPGA based QPSK modulator with analog filters, the proposed system has many advantages over traditional QPSK modulators such as reduced cost, better stability ...

In the field of modern mobile communication, (Quadrature Phase Shift Keying) QPSK modulation technology is widely used, which has a great advantage that it can work normally in a limited frequency ...

Modulation Techniques: Implements BPSK, QPSK, 16-QAM, 64-QAM, and OFDM. Performance Metrics: Compares BER and spectral efficiency across modulation schemes. Visualization: Includes plots for BER vs ...
