- Ethernet Source with SimEvents
- License: Freeware

When audio or video is transmitted over an Ethernet network, the data is usually transmitted in bursts of packets with long idle times in between bursts. SimEvents is a good tool for modeling those types of sources and studying the effects of queue size and server times on the audio or video transmission. This model uses an internet radio file captured from Ethereal as a source, and transmits data with the packet lengths and source times defined in that file. You can study the effects of changing the FIFO Queue size or serviceTime values on the number of dropped packets for the selected source.

The task of this work is to extract a signal radiating from a specific direction in the presence of a jamming signal being transmitted at same frequency. There are four cases in the first case transmitter and jammer are in different directions and are at equal range from receiver but the jammer is switched off that is there is no interference signal. In the second case the transmitter and jammer are in different directions but at equal range from the receiver. In the third case the transmitter and jammer are in the same direction but at different ranges from the receiver. In the last case simulation is done when the transmitter and jammer are very close to each other and at equal ranges.

- BER vs. SNR of a binary antipodal communication system
- License: Freeware

A uniform random number generator is used to generate the binary information sequence from the binary data source. The sequence of '0's and '1's is mapped into sequence of +E and E where E represents the signal energy. E may be normalized to unity The Gaussian noise generator is used to generate the sequence of '0' mean and variance dcDo2 Gaussian random numbers. The detector compares the random variable 'r' with the threshold of '0'. If r > 0, the decision is made that the transmitted bit is '0'. If r < 0, the decision is made that the transmitted bit is '1'. The output of the detector is compared with the transmitted sequence of information bits and the bit errors are counted.

This script is intended to illustrate the concepts of eyediagramm, constellation, ISI and to understand the effects of additive noise power, channel frequency band restriction, number of possible states within a symbol period, affecting the quality of the transmission. Three methods are employed for low-pass filtering: - classical low pass filter (actually two order Butterworth) creating ISI. - raised cosine filter in order to illustrate the possibility of suppress ISI . - Pseudo filtering by increasing risetime and falltime of ideal rawcode . Levels of signal transmitted as well as noise level are variables, allowing thus the possibility to show the effects of the number of states by symbole time on the possibility to recover without error the information in a given Signal/Noise environment.

- BPSK Simulation for AWGN & Rayleigh Channels
- License: Freeware

BPSK SYSTEM SIMULATION We simulate the generation of random variables r0 and r1, which constitutes the input to detector. We begin by generating a binary sequence of 0?s and 1?s that occur with equal probability and are mutually (statistically) independent. For this, we use a Random number generator that generates a uniform random number between 0 and 1. If the number generated is in range (0, 0.5), the binary source output is 0 else it is 1. if 0 is generated, then r0=E+n0 and r1=n1. if a 1 is generated r0=n0 and r1=E+n1. The additive noise components n0 and n1 are generated by mean of two gaussian noise generators there means are zero and there variances, doDl2 = E*N0/2.
