Abstract :
A 2 Gbps QPSK modulator and demodulator were developed and BER performance was evaluated over a millimeter wave data channel. The error rate measurements taken with the breadboard equipment showed system performance to be less than 2 dB from theoretical at an error rate of 10-5. Additionally, a second QPSK modulator was constructed and combined with the first to generate 4 Gbps QASK data for future evaluation.
