Performance comparison of the BPSK and QPSK modulation techniques on FPGA

摘要

The paper presents the comparison performance in terms of error performance between two modulation techniques, the BPSK and QPSK modulation. Both modulations were implemented on the Spartan 3E Starter Kit board. In order to compare the error performance of the two modulation techniques, it is necessary to express the error performance in terms of the average energy per bit (Eb). A brief description of theoretical aspects of the BPSK and QPSK modulations is also illustrated in the paper.
