Reduction of intersymbolic interference using the eigenanalysis method and linear antenna array

This work presents results of a study concerning joint use of antenna arrays and eigenanalysis method for inter symbolic interference reduction without using a training sequence. The cancellement capacity of the eigenanalysis method is applied to reduce the multipath propagation effect, beamforming the path of the desired signal and attenuating undesirable paths. This equalization is analyzed in frequency and time domain and results show that the method can be used to combat intersymbolic interference. Besides, the curve of the estimated bit error rate (BER) shows that antenna arrays and eigenanalysis method can be utilized to improve the equalization efficiency.
