A New-Trend Model-Based to Solve the Peak Power Problems in OFDM Systems
New-Trend Model-Based Peak Power Problems OFDM Systems
2009/9/4
The high peak to average power ration (PAR) levels of orthogonal frequency division multiplexing (OFDM) signals attract the attention of many researchers during the past decade. Existing approaches th...
Direct amplification of picosecond pulses in erbium fibre to 127 kW peak power without pulse break-up
Direct amplification picosecond pulses erbium fibre
2015/7/30
Picosecond pulses are directly amplified in a core pumped erbium fibre with effective area 1170- μ m 2 to record diffraction limited 67- nJ pulse energy and 127- kW peak power without pulse break-up.
Measurement of Non Linear Thresholds in O-OFDM Systems with Respect to Data Pattern and Peak Power to Average Ratio
O-OFDM Systems Respect Peak Power Average Ratio
2015/7/30
We investigated the non linear threshold of a coherent O-OFDM system. An improvement for NLT of about 2.5dB was demonstrated either by reducing the data pattern length or clipping of the OFDM signal.
