Dalam makalah ini, kami mencadangkan pengurangan PAPR baharu dengan menggunakan gabungan jujukan penghantaran separa (PTS) dan kaedah pengurangan kuasa puncak adaptif (APPR) dengan teknik maklumat sisi berkod (SI). Kaedah ini digunakan dalam sistem Orthogonal Frequency Division Multiplexing (OFDM). OFDM menggunakan sub-pembawa ortogonal untuk modulasi data. Sub-pembawa ini secara tidak dijangka membentangkan Nisbah Kuasa Puncak kepada Purata (PAPR) yang besar dalam beberapa kes. Untuk mengurangkan PAPR, urutan data input disusun semula oleh PTS. Kaedah APPR juga digunakan untuk mengawal tahap puncak isyarat modulasi oleh algoritma penyesuaian. Kaedah pengurangan yang dicadangkan terdiri daripada dua kaedah ini dan menyedari kedua-dua kelebihan pada masa yang sama. Untuk menjadikan keadaan optimum pada PTS untuk pengurangan PAPR, kos pengiraan yang agak besar mesti dituntut dan dengan itu adalah mustahil untuk mendapatkan PTS optimum. Dalam kaedah yang dicadangkan, dengan menggunakan keadaan pseudo-optimum dengan teknik SI berkod, jumlah kos pengiraan menjadi berkurangan secara drastik. Dalam keputusan simulasi, kaedah yang dicadangkan menunjukkan penambahbaikan pada PAPR dan juga mendedahkan prestasi tinggi pada kadar ralat bit (BER) sistem OFDM.

Abstract: In this paper, we propose a new PAPR reduction by using the hybrid of a partial transmit sequences (PTS) and an adaptive peak power reduction (APPR) methods with coded side information (SI) technique. These methods are used in an Orthogonal Frequency Division Multiplexing (OFDM) system. The OFDM employs orthogonal sub-carriers for data modulation. These sub-carriers unexpectedly present a large Peak to Average Power Ratio (PAPR) in some cases. In order to reduce PAPR, the sequence of input data is rearranged by PTS. The APPR method is also used to controls the peak level of modulation signals by an adaptive algorithm. A proposed reduction method consists of these two methods and realizes both advantages at the same time. In order to make the optimum condition on PTS for PAPR reduction, a quite large calculation cost must be demanded and thus it is impossible to obtain the optimum PTS. In the proposed method, by using the pseudo-optimum condition with a coded SI technique, the total calculation cost becomes drastically reduced. In simulation results, the proposed method shows the improvement on PAPR and also reveals the high performance on bit error rate (BER) of an OFDM system.
