Figure 5.6. Block diagram of digital backpropagation. 5.2.1.3 Application of digital backpropagation-based DSP in optical transmission experiments Assuming the predictions of the “capacity crunch” mentioned in the Introduction [1] will indeed take place, an increase in the optical transport capacity...
Figure-1: L Band Satellite modem Block diagram (Modulator part) As shown in the modem block diagram, it consists of two cards one M&C Card and another modulator/demodulator card. M&C Card houses Micro-Controller (DS80c320), EPROM, NVRAM and other discrete components. Modulator/demodulator is a...

block error probabilityViterbi decodingtrellis diagramThis method is applied for some specific 8-PSK Ungerboeck codes with 24, 25, and 26 states. the results show that the values obtained by this method are very close to those by simulation. It is concluded that this method is very effective....
The equalizer's role is to compensate for such effects.FIG. 1depicts a block diagram of a basic communication system. Data from a source100is fed to a modulator102that in turn passes the modulated data to a wireless communication component104. The communication signal is then transmitted by a...
When I create this Simulink block that time there is no error but unfortunately when I put this block in the existing 16-QAM or PSK it does not work properly to compare 16-QAM. Please receive my attach 16-apsk file's link When I run this Simulink d...
