Here, the authors are proposing the FPGA based QPSK modulator with analog ... They have designed the system using VHDL codes in Xilinx & analog filter simulation in Matlab. Catch up on the latest ...

This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the ...
