Maybe this is not a good forum to ask this question, but someelectronics guru please provide some suggestions to my problem ? I amexperimenting with a QPSK modulator - demodulator system, and myquestion is:if the data bits are arriving at 1 MHz, what would be an ideal carrierfrequency ? I think the Nyquist criteria should hold, but somewhatconfused. Any hints, suggestions would be of great help. Thanks inadvance.
