Abstract

The Channel estimation is improving the BER performance in the OFDM systems and considers an important part in OFDM systems. It can be employed for the purpose of detecting received signal, improving the capacity of OFDM. In this paper, studied and analyzed the effects of channel estimation, by using Least-Squares Error (LSE) algorithm in OFDM system, where change in the transmitted power per pilot symbol in the FFT-OFDM system. A mathematical derivation of the algorithm LSE channel Estimation by control on the value of the transmitted power per pilot symbol is also presented.
