Reducing peak to average power ratio of OFDM by using selected mapping
High speed data transmission transmitter rf power amplifier mapping
2014/12/31
Orthogonal frequency division multiplexing (OFDM) has become the most popular modulation technique for high speed data transmission. However, high peak to average power ratio (PAPR) is a major drawbac...
Monitoring of Orthogonal Polarization Power Ratio due to PDL using Intensity Tones in Polarization Multiplexed Signals
Fiber optics communications Fiber optics links subsystems
2015/5/25
We demonstrate a technique for monitoring orthogonal polarization power ratio (OPPR) occurring in WDM polarization-multiplexed signals due to PDL. We employ low-frequency intensity tones to estimate t...
Reduced Complexity Precoding Based Peak-to-Average Power Ratio Reduction Applied to Optical Direct-Detection OFDM
Complexity Precoding Power Ratio Optical Direct-Detection OFDM
2015/8/4
DCT based precoding is proposed for PAPR reduction to improve the performance of optical OFDM at limited precoding complexity. Effective PAPR reduction and the resultant OSNR performance are shown.
