A simulation of MPSK communications system performance in the presence of wideband noise and co-channel interference
MetadataShow full item record
The purpose of this research is to model digital communications systems in the time domain using MATLAB Simulink and the Communications Toolbox and to determine and verify the system performance in the presence of additive noise and interference. While the theoretical results are available for the assessment of the influence of wideband gaussian noise on the performance of a digital communications system, determining the performance of a system in the presence of noise and interference requires a computer simulation. The time domain modeling allows the visualization of communication signals at various stages of transmitters and receivers and Monte Carlo type simulations to establish the bit error rates under realistic conditions (noise, interference) and for different values of transmitter/receiver parameters, different channel parameters and different types of interfering signals. It should be noted that the simulation does not account for system non-linearities.
