Research on modified selected mapping technique for PAPR reduction and reception performance improvement in 8QAM-OFDM optical access systems
Orthogonal frequency division multiplexing has been regarded as one of the promising technologies for the optical access systems application. However, high peak-to-average power ratio will cause the signal distortion and enable the used amplifier to operate in nonlinear section.
In this paper, a modified selected mapping technique is introduced for reducing the peak-to-average power ratio and enhancing reception performance of the downstream 8QAM-OFDM signals in optical access systems.
Compared with the traditional selected mapping technique, the PAPR value of 8QAM-OFDM optical downstream signals with 128 subcarriers is reduced by almost 2 dB using modified SLM when the complementary cumulative distribution function probability value is 10?2. Moreover, the bit error rate performance will be improved, while 10Gbit/s 8QAM-OFDM optical downlink signals are transmitted over single mode fiber with different access length.
Hence, the proposed scheme becomes more efficient for the future optical orthogonal frequency division multiplexing access systems.
期刊介绍：
Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry.
Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research.
The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics.
The journal covers both fundamental and applied topics, including but not limited to:
Classical and quantum optics
Light/matter interaction
