Simulink Model for BPSK to find BER vs EbNo curve under AWGN channel using Discrete-Time Integrator.

The model represents the baseband simulation of the BPSK system in Matlab Simulink. It consists of a Bernoulli Binary generator which generates a binary sequence {1,0,1,1,0},sample and hold to sample the bit sequence, Baseband BPSK modulator which convert sequence into {-1,1} form, AWGN Channel to introduce noise in the signal//bit, the demodulator consist of Discrete time integrator which integrate the noise sample till sample time (i.e 1s), look-up table which convert the signal into {1,0} form, Error block to calculate the BER. The simulink file is used to run the model which give the BER curve Simulated and theoretical.
Earlier model don't used such kind of demodulation they directly used BPSK Baseband demodulator block.
