| Abstract: | Smart antenna systems have recently played a central role in removing narrowband multiple access interference in wireless communications. However, if these adaptive systems are proposed for wideband wireless communications the addition of frequency compensation techniques are needed. This paper particularly introduced Spectral Decomposition, Focussing Algorithm and Interpolating Algorithm. Then discussed the simulation results. And the results tell us in system which using frequency compensation technique , the performance can be improved, the Interpolating Algorithm is the best. This indicated that this kind of frequency compensation technique is valuable in using. |
