Lab 12: Quadrature Phase-Shift Keying

This is lab 12 of 12 in the course
by Dr. Bruce Black | Rose-Hulman Institute of Technology
In this lab project we introduce quadrature phase-shift keying (QPSK), a variation on binary phase-shift keying that encodes two bits of data into each symbol. Using QPSK, we can transmit data at twice the rate, without increasing the channel bandwidth. There will be some loss in performance, however, as somewhat more transmitted power will be needed to maintain a given bit error rate in the presence of noise.
