Simulation of bpsk bit error rate and bit error rate

Key focus: Simulate bit error rate performance of Binary Phase Shift Keying (BPSK) modulation over AWGN channel using complex baseband equivalent model in Python & Matlab. This post contains interactive python code which you can execute in the browser itself. The passband model and equivalent. There are lot digital modulation Channel techniques that are well flourished in the communications field, selection of a suitable modulation technique for an application depends on many factors like Bit error rate, data rate, design Demodulator/ complexity etc. Make a table recording the value of $frac {E_b} {N_0}$ and the corresponding BER.
