Abstract

In this study, a new proposal has been made about the frequency multiplication method. In the modified QPSK modulator developed for data transmission used frequency multiplication, the constellation diagram has been modified. It has been shown that data transmission can be provided with a little power loss without any change on the receiver side in a real-time system through the change perform in the transmitter. This proposed method was experimentally implemented using USRP. As a result of the performance analysis, BER graphs and eye diagrams obtained by applying both standard QPSK and proposed modified QPSK modulation are presented.
