“…The pulse shaping function was applied at the transmitter. Flat fading Rayleigh channel was used where each channel response that is Rayleigh distributed [25] with adding addictive white Gaussian noise (AWGN). The parameters used in this simulation were based on fixed wireless worldwide interoperability for microwave access (WiMAX) standard as shown in Table 1.…”

The weakness of the orthogonal freuency division multiplexing (OFDM) system is susceptible to the existence of carrier frequency offset (CFO) which causes the emergence of inter carrier interference (ICI) which causes a degradation of performance OFDM systems. This study aims to apply the suggested rectangular (REC) pulse and improved sinc-power (ISP) pulse shaping methods on OFDM system and determines ICI reduction with the effects of CFO over flat fading Rayleigh channels. The performance of each pulse shaping method is evaluated and compared based on parameter ICI power vs. normalized frequency offset, signal to interference ratio (SIR) vs. normalized frequency offset and bit error rate (BER) vs. energy bit per noise (Eb/No). The simulation result in terms of BER vs. Eb/No indicated that REC and ISP pulse shaping has better performance dealing with ICI reduction compared to OFDM system no applied pulse shaping. In addition, the ISP is able to mitigate ICI better than REC.

“…It is due to the higher the offset frequency effected to the OFDM system so that the ICI power generated will also be greater. From the simulation results, it can also be seen that BER performance of OFDM system with ISP pulse was able provided better performance than REC pulse [25][26][27].…”
