Daftar Isi:
- The combination OFDM (orthogonal frequency division multiplexing), and pulse shaping are expected to reduce the effects of Inter Carrier Interference (ICI) and error occurred. This study aimed to compare the performance of OFDM without pulse shaping nd OFDM with pulse shaping Improved Sinc Power (ISP) pulse through Frequency Selective Fading channel, in terms of BER (bit error rate) vs. Eb/No (energy per bit to noise power spectral density ratio). This study implemented simulation using Matlab R2018a. The results of the simulation OFDM with ISP pulse system performance has better results than OFDM without pulse shaping. In the transmission Frequency Selective Fading channel, to reach 10-1 BER value in OFDM with ISP pulse was required Eb/No of 2 dB. While the OFDM without pulse shaping systems required Eb/No 10 dB. Keywords — OFDM, Pulse Shaping, ICI, ISP pulse, Frequency Selective Fading.
- Kombinasi antara sistem OFDM (orthogonal frequency division multiplexing) dan Pulse Shaping mampu mengurangi Inter Carrier Interference (ICI) dan error yang terjadi. Penelitian ini bertujuan untuk mengetahui perbandingan performansi dari sistem OFDM tanpa pulse shaping dan OFDM dengan pulse shaping Improved Sinc Power (ISP) pulse yang melalui kanal Frequency Selective Fading, ditinjau dari BER (bit error rate) berbanding Eb/No (energy per bit to noise power spectral density ratio). Penelitian ini menggunakan metode simulasi dengan menggunakan program Matlab R2018a. Hasil dari simulasi didapat unjuk kerja sistem OFDM dengan pulse shaping ISP pulsememiliki hasil yang lebih baik dari OFDM tanpa pulse shaping. Pada kanal transmisi Frequency Selective Fading untuk mencapi nilai BER sebesar 10-1 sistem OFDM dengan pulse shaping ISP pulse dibutuhkan Eb/No sebesar 2 dB. Sedangkan pada sistem OFDM tanpa pulse shaping dibutuhkan Eb/No sebesar 10 dB. Kata Kunci — OFDM, Pulse Shaping, ICI, ISP pulse, Frequency Selective Fading.
