This document summarizes a study that compares the Bit Error Rate (BER) and error generation of Binary Phase-Shift Keying (BPSK) modulation versus other Phase-Shift Keying (PSK) modulation techniques through computer simulation. The simulation results show that BPSK modulation has a consistently low BER and generates errors at a steady slow rate, even over long simulation times, making it preferable when minimizing errors and distance are important. In contrast, the other PSK modulation techniques tested (QPSK, 8-PSK, 16-PSK) have higher and more fluctuating BER values over time and generate errors at a faster increasing rate.
