Modeling QAM in Matlab
It requires a software engineer, with the experience of the ESS, to model the Matlab QAM moduleizer/demodulator with the further transmission/receivement of the modified signals via the computer's sound card.
Bit flow rate of 2.5-3qbit/s, frequency of 1500-2500Hz.
Offer a price and a time frame.
