Abstract |
|
Orthogonal Frequency Division Multiplexing (OFDM) is a hopeful technique for attaining high data rates in mobile environment because of its multicarrier modulation. As the sub carriers are orthogonal in OFDM, the spectrum of each carrier has a null at the center frequency of each of the other carriers in the system. But in time varying channel the orthogonally between subcarriers are distorted due to Doppler Spread (DS) which introduces the Inter Carrier Interference (ICI) that diminishes the system performance. To enhance the OFDM system performance over time varying channels, an ICI self-cancellation scheme with hew radix FFT at receiver is implemented. The OFDM pruning at the receiver side using hew FFT is suggest for ICI reduction techniques in the thesis work. The work is implemented using MATLAB. Simulation and the outcome is measure in terms of BER and Twiddle factor count. |
