Radio Over Fiber System

AbstractAdvanced modulation schemes play a vital role for RoF communication system for different channels. Keeping into view the same, in this paper a DQPSK (Differential Quadrature Phase Shift Keying) based radio over fiber system is proposed. Appropriate value of FWHM is also concluded for faithful communication.

Ber Performance

Focused on the communication system of differentially encoded binary phase-shift keying (DBPSK/2DPSK), this paper studies on the influences of inter symbol interferences (ISI) on the bit error rate (BER) performance and derives the BER expression that is applicable for arbitrary sending probabilities of binary symbols using the knowledge of integration and probability theory, which is then demonstrated to be correct by the Monte Caro simulation method.

Ber Performance

The problem of extremely low speed communication (ELSC) system in the computer network based on multi-position phase shift keying (MPPSK) is considered in this paper. The realization of extremely low speed system is described, and preliminary simulation results of this system are conducted. The BER performance of the MPPSK-based ELSC system is compared with that of MSK modulation, which is commonly used in the ELSC system. Furthermore, the simulation results show that MPPSK-based ELSC system with higher spectrum efficiency has better BER performance than that of MSK modulation, which confirms the efficiency of the proposed system.
