We present experimental results on ergodic channel capacity of single input single output (SISO) free-space optical (FSO) communication link. Furthermore, we present simulation results on bit error rate (BER) performance of M-ary quadrature amplitude modulation (M - QAM) considering the average received irradiance. In the simulation, effects of different parameters such as constellation size, wavelength...
Long Term Evolution (LTE) has adopted Single Carrier Frequency Division Multiple Access (SCFDMA) technique for uplink and Orthogonal Frequency Division Multiple Access (OFDMA) for downlink. SCFDMA is often called as Discrete Fourier Transform (DFT) spread OFDMA. In this paper, Wavelet based SCFDMA is proposed for analyzing Bit Error Rate (BER) performance. Analysis is carried out using different wavelets...
In this article, different modulation format RZ, CRZ, CSRZ and NRZ on free space optical communication system has been investigated. It has been observed that external modulation gave us better performance in comparison to direct modulation because direct NRZ spectrum has a strong carrier component compared to external modulated NRZ. Simulation results show that RZ modulation format is best for long...
