Abstract: Call drop out is one of the most annoying problems in
mobile communications. Over the years, many strategies have been proposed
to solve the problem of call drop out, but it is still prevalent. One
of the important reasons for call drop outs is high Bit Error Rate (BER).
In this study, our intent is to reduce the call drop out by decreasing
the BER based on Empirical Mode Decomposition (EMD). Thereafter, we introduce
a new signal processing subsystem at the receiver section to decrease
BER and thereby improve the end-to-end performance of the system. Our
simulation is valid specifically for Code Division Multiple Access (CDMA)
with QPSK modulation, although it can be extended to any cellular network.
Our simulation proves that the new signal processing subsystem improves
the BER performance. |

I read the paper and found it very useful.I would certainly like to work on this area.IMF is very useful concept to analyze signals. |
