Experimental 2 GBPS MM wave system and 4 GBPS QASK modulator
Abstract
A 2 GBPS modulator and demodulator were developed and BER performance was evaluated over a millimeter-wave satellite channel. Error rate measurements taken with breadboard equipment showed system performance to be less than 2 dB from theoretical values at an error rate of 0.00001. In addition, a second QPSK modulator was constructed and combined with the first to generate 4 GBPS QASK data for future evaluation.
