| Summary: | Telecommunication channels may bring destructive effects for the signals
trasmitted over it. One of them is the multipath delay effect which may lead to
Inter Symbol Interference (ISI).
OFDM systems avoiding ISI by having guard interval between each
symbols. To completely avoid ISI, the duration of guard interval should be longer
than the multipath delay effect caused by the channel. However, lengthen the CP
duration will reduce the efficiency of overall OFDM performance. Another
approach is by using Time Domain Equalization (TEQ) MMSE-UEC on OFDM
receiver. It will compensate the channel to shorthen the multipath delay in order
to make it shorter than CP duration.
Simulation results show that the TEQ MSE-UEC equalization is able to
compersate the ISI, indicated by the decreasement of BER from 15,026 % to
0,286458 %.
