Abstract
In this project the above mentioned students are going to study the Inter Symbol Interference (ISI) on base band digital transmitted data.
ISI is one of the fundamentals problems in digital communication system that arises due to the nature of dispersive channel. One way to reduce the effect of ISI is to reduce the bit rate of the transmitted symbols. However this solution is not preferred since the trend in modern communication systems requires large transmission rate.
An alternate solution to minimize the effect of ISI is to find the inverse impulse response of the channel therefore equalize the channel and reduce the effect of ISI.
In this project equalization techniques such as decision feedback and blind equalization will be investigated over a dispersive channel. The study of these equalization techniques will be applied to quadrature phase shift keying modulated data.
In order to accomplish this project, students will simulate a randomly generated bit stream with and without the use equalizer inserted in the receiver by using MATLAB. After the successful completion of the simulation students may use real data transmission (text file between two PCs) by using DSP kits in the next semester.
