SFBC with clipping and filtering as a transmit diversity technique in SC - FDMA
The paper presents Space-Frequency Block Coding (SFBC) as a transmit diversity technique in Single Carrier Frequency Division Multiple Access (SC-FDMA). SC-FDMA is known as a low Peak-to-Average Power Ratio (PAPR) modulation technique. SFBC requires changing the order of the samples in the frequency domain, which results in increase of the PAPR. Because of that, additional clipping and filterin...
متن کاملChannel Capacity of SC-FDMA Distributed Antenna Network Using Transmit Diversity
あらまし 送信アンテナを空間的に十分離して配置する分散アンテナネットワーク(DAN) は伝搬損失,シャドウ イング損失および周波数選択性フェージングの影響によって生じる問題を解決可能な無線ネットワークである.本 論文では,シングルキャリア周波数分割マルチアクセス(SC-FDMA) DAN の 2 次元注水(2D-water filling : 2D-WF) 重みを用いる下りリンク送信ダイバーシチにおける周波数スケジューリングについて提案している.ここで, 2D-WF 重みは送信アンテナ次元では最大比送信(MRT)規範に基づく電力配分を,周波数次元では注水定理に基づく 電力配分を行う送信重みである.モンテカルロ数値計算により周波数スケジューリングがチャネル容量の分布に与 える影響について検討を行っている. キーワード 分散アンテナネットワーク,送信ダイバーシチ,チャネル容量,周波数スケ...
متن کاملReduction of Phase Noise Influence in MISO SFBC SC-FDMA System
It is very important to achieve high performance in the SC-FDMA (single carrier frequency division multiple access) system that is used for LTE (long term evolution) and LTE-advanced system. To simultaneously resolve ICI(inter-subcarrier interference) and PAPR(peak to average power ratio) problem, focused on the two transmit(Tx) / one receive(Rx) antenna configuration, phase noise influence on ...
متن کاملPerformance enhancement of SC-FDMA systems using a companding technique
In this paper, a companding technique is proposed to effectively reduce the peak-to-average power ratio (PAPR) in single-carrier frequency division multiple access (SC-FDMA) systems. By companding the samples with large amplitudes, while enhancing those with small amplitudes, a significant reduction in the PAPR can be achieved. The performance of the proposed SC-FDMA with companding system is s...
متن کاملCorrelative Coding with Clipping and Filtering Technique in OFDM Systems
The major setbacks of Orthogonal Frequency Multiplexing (OFDM) is its peak-to-average power ratio (PAPR) and intercarrier interference (ICI). The occurrence of these factors restricts its application. Here, the clipping and filtering PAPR reduction technique is k i n g investigated to reduce the PAPR and out-of-band radiation simultaneously by implementing correlative &g. This paper focuses on ...
