BPSK Modulation And Demodulation Complete Matlab Code With Explanation. Binary Phase Shift Keying BPSK is a type of digital modulation technique in which we are sending one bit per symbol i. Hence, the bit rate and symbol rate are the same. Depending upon the message bit, we can have a phase shift of 0o or 1. For example, we can have the following transmitted band pass symbols or. Where E is the symbol energy, T is the symbol time period, f is the frequency of the carrier. Using Gram schmidt orthogonalization, we get a single orthonormal basis function, given as Hence, the resulting constellation diagram can be given as Constellation Diagram Of BPSK Signal.

There are only two in phase components and no quadrature component. Now, we can easily see that the two waveform of So and S1 are inverted with respect to one another and we can use following scheme to design a BPSK modulator BPSK modulator.

Then NRZ waveform is generated by up sampling these impulses. Afterwards, multiplication with the carrier orthonormal basis function is carried out to generate the modulated BPSK waveform. Demodulator Design We do coherent demodulation of the BPSK signal at the receiver. Coherent demodulation requires the received signal to be multiplied with the carrier having the same frequency and phase as at the transmitter. The phase synchronization is normally achieved using Phase Locked Loop PLL at the receiver. PLL implementation is not done here, rather we assume perfect phase synchronization. Block diagram of BPSK modulator is shown in the figure below. After the multiplication with the carrier orthonormal basis function, the signal is integrated over the symbol duration T and sampled. Then thresholding is applied to determine if a 1 was sent ve voltage or a 0 was sent ve voltage. BPSK Receiver Design. The Matlab simulation code is given below. Here for the sake of simplicity,  the bit rate is fixed to 1 bits i. T1 second. It is also assumed that Phased Locked Loop PLL has already achieved exact phase synchronization. Nb is the number of bits to be transmitted. T1 Bit rate is assumed to be 1 bits. Rb is the bit rate in bitssecond. Microsoft Office 2010 Pro Plus Activated'>Microsoft Office 2010 Pro Plus Activated.
