Reduksi Peak-To-Average Power Ratio Pada Sistem STBC MIMO-OFDM dengan Metode Selected Mapping dan Partial Transmit Sequence

Abstract: Ab s tra kTeknik OFDM merupakan teknik multicarrier yang mengefisienkan bandwidth. Penggunaan teknik OFDM dapat mengatasi multipath fading dan intersymbol interference (ISI). Namun demikian, OFDM mempunyai dua kelemahan, salah satunya adalah peak-to-average power ratio (PAPR) yang tinggi. PAPR yang tinggi akan menyebabkan distorsi nonlinear pada high power amplifier (HPA) karena HPA membatasi keluaran dengan nilai tertentu dan mengurangi efisiensi daya amplifier. Oleh karena itu, PAPR yang tinggi harus direduk… Show more

“…A technique that can be used to overcome multipath fading is the use of multi-antenna on the transmitter and receiver which is often called the Multiple Input Multiple Output (MIMO) technology. MIMO technology was first introduced by Jack Winters of Bell Laboratories in 1984 with the intent to overcome multipath fading [2]. MIMO can provide diversity gain, multiplexing gain and can increase channel capacity without the need to increase bandwidth and transmit power.…”
