? Preparation of the one containing the transmission and reception of QAM transmission module
? Complex baseband simulation and real bandpass simulation were used in two forms
? When the simulation of the complex baseband oversampling rate 4 times, real bandpass simulation over-sampling rate of 20 times the real bandpass simulation, the carrier frequency is 4 times the symbol rate
? Originator using the square root raised cosine filter roll-off factor of 0.5
? Draw Eb/N0 = 15dB received waveform (received before filtering), take the 100 samples
? Draw originator output eye diagram and eye diagram after the receiving end matched filtering plus noise (painted eye diagram)
? Statistics symbol error rate and bit error rate and Eb/N0 relationship, draw curves, and compared with the theoretical calculation of the curve Platform: |

Description: Code to simulate the effect of Inter Symbol Interference. The first figure plots the pulse amplitude modulation (PAM) of input sequence. Then a raised cosine pulse is used as pulse shaping signal for transmission. The next figure shows the effect of ISI with and without noise with the help of eye diagram.-Code to simulate the effect of Inter Symbol Interference.
