Study of the BER performance in RoF-OFDM system modulated by QAM and PSK
نویسندگان
چکیده
Orthogonal frequency division multiplexing (OFDM) is considered as a one of the essential components in most of recent telecommunication systems. To maintain a high bit rate and provide a high bandwidth, using the OFDM as a modulation format in RoF system is preferred over other modulation formats. In this paper, up-converting a 20 Gb/s and a 30 Gb/s OFDM signal on a 20-GHz microwave carrier over 40 km SMF was applied under a different modulation methods of OFDM such as QAM and PSK in order to study the BER performance in all proposal cases.

In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...

Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
