“…In OCDMA, most important consideration are code design. Multiple Access Interference (MAI) is the interference from other users transmitting at the same time, which will limit the effective error probability with the presence of noise in the overall system [6]. * Corresponding author: eng_fazz@yahoo.com In OCDMA, PIIN will increase between codes sequences because of inappropriate cross users and cannot be improved by increasing the transmitted power [7].…”

“…Recent studies suggest ways to solve LOS line of sight problems with minimal bit-error-rate (BER) performance in FSO communication system under worst interference conditions [12]. But the increasing of laser power can resolve this problem up to some point [13]. As the transmitter reaching maximum power limit, the bandwidth or transmission distance of the physical links which are under severe weather conditions such as heavy haze has to be reduced.…”

Abstract. In this paper, the performance of downlink design utilizing the free space optic (FSO) is presented. The permissible BER of 10 -58 is achieved when the system utilized 40 cm aperture diameter. The highest system sensitivity will lead to less error and enable more transmission output. The result revealed, at a bit rate 155Mbps and effective received power -27.5 dBm, FSO downlink system at bit rate 155 Mbps improved by 13% as compared to 1.5 Gbps and 2.5 Gbps in single transmission line. It is truly shown that, the FSO system utilized 155 Mbp/s with 40 cm aperture diameter shown good performance of a reliable FSO downlink system.

Abstract. This paper presents a realization of Wavelength/Time (W/T) Two-Dimensional Modified Double Weight (2-D MDW) code for Optical Code Division Multiple Access (OCDMA) system based on Spectral Amplitude Coding (SAC) approach. The MDW code has the capability to suppress Phase-Induce Intensity Noise (PIIN) and minimizing the Multiple Access Interference (MAI) noises. At the permissible BER 10 -9 , the 2-D MDW (APD) had shown minimum effective received power (Psr) = -71 dBm that can be obtained at the receiver side as compared to 2-D MDW (PIN) only received -61 dBm. The results show that 2-D MDW (APD) has better performance in achieving same BER with longer optical fiber length and with less received power (Psr). Also, the BER from the result shows that MDW code has the capability to suppress PIIN ad MAI.
