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.
<br />Earlier model don't used such kind of demodulation they directly used BPSK Baseband demodulator block.</p>Gaurav Sharmahttp://www.mathworks.com/matlabcentral/profile/authors/5429468-gaurav-sharmaMATLAB 8.1 (R2013a)Communications System ToolboxMATLAB CompilerRF ToolboxDSP System ToolboxSignal Processing ToolboxSimulinkMATLABfalsetag:www.mathworks.com,2005:FileInfo/13202002-02-12T19:33:52Z2013-09-26T20:16:42ZAnalog / Mixed Signal ExamplesExtensive collection of examples for analog and mixed signal design work.<p>This package is a continues to be expanded. It has been modified to work with R2013B. Examples include: VCO with user defined phase noise, impedance matching and filter design, interleaved ADC, clock multiplying delay lock loop, clock recovery for NRZ data. Further examples include: fractional N PLL, digital fractional N PLL, Sigma-Delta ADC, Sigma-Delta ADCs with SINAD Measurement block, elliptic LC filter design, RF blockset examples, numerous Circuit Level examples such as switching power supplies, class D H bridge audio amp, active filters, passive filters, simulated vector network analyzers. </p>
<p>Package includes an "Example Navigator" which makes it a snap to select and run any of the 60+ models. </p>

<p>This simple model illustrates some relationships inherent in the conversion...</p>
<p>* Length of impulse response = number of sub bands</p>
<p>* Total bandwidth = 1/sample time</p>
<p>* sub band bandwidth = total bandwidth / number of sub bands</p>
