Use4-QAM baseband modulationto send 20 bits (bits10010 01010on I and bits11101 01001on Q) at an overall transmission rate of 2 bits per millisecond using three pulse shapes given below. Use a carrier whose frequency is 10kHz. Plot the following signal in time and frequency domain for ea...
This MATLAB function returns a demodulated signal, Z, given quadrature amplitude modulation (QAM) signal Y of modulation order M.
This post defines the Modulation Error Ratio (MER) for QAM signals, and shows how to compute it. As we’ll see, in the absence of impairments other than noise, the MER tracks the signal’s Carrier-to-Noise Ratio (over a limited range). A Matlab script at the end of the PDF version...
Same channel i.e. AWGN is used for both the digital modulation techniques. Mainly use of MATLAB R2014a is carried out for complete system simulation and same will be verified using MATLAB simulation.Saloni MunjalHimani LathwalR. KumarV. Verma...
