1. INTRODUCTION
Coding schemes play a major role in analyzing the performance of OCDMA system. In this
direction many researchers have proposed signature sequences in different dimensions [2, 7, 11,
and 12]. We had modeled these sequences based on algebraic coding theory in two categories
Model A and Model B [1, 3, 4, and 5].
In this paper we have used the OPTSIM simulation tool to evaluate the performance of
transmission of five users based on Model B using optical orthogonal codes, Cubic Congruent
Operator and Linear Congruent Operator from algebra theory with varying bit rates. The paper is
organized as follows. In Section II, Mathematical Modeling of 3D OCDMA system along with
Model B is discussed. Section III shows the 3D Codeset and calculates the system parameters
required for simulation. Section IV shows the implementation details on the simulation software
along with the results for five users with 5 WDM × 4 TDM × 5 CODE Channel 3D OCDMA
system based on Model B using GF (5) with varying attenuation at the front end of the receiver at
variable bit rates. Finally conclusion is drawn in section V.](https://image.slidesharecdn.com/performanceanalysisoftransmissionof5usersbasedonmodelbusinggf5withvaryingbitratesfor3docdmasystem-131007012205-phpapp02/85/Performance-analysis-of-transmission-of-5-users-based-on-model-b-using-gf-5-with-varying-bit-rates-for-3-d-ocdma-system-1-320.jpg)

In Model B, OOC code is used to spread in time domain and is taken from literature C=
1011000100000 is a (13,4,1) code with c={0,2,3,7} where n=13,w=4 and λa = λc =1, coding
scheme of cubic congruent operator based on Table 1 is used for spreading in spectral domain and
coding scheme of linear congruent operator is used for spreading in spatial domain as shown in

3. 3D CODESET AND OCDMA SYSTEM
In accordance with Model B shown in Fig 1, the signature sequence is spreaded as follows. For
temporal spreading: Optical orthogonal code is taken from literature C= 1011000100000 is a
(13,4,1) code with c={0,2,3,7} where n=13,w=4 and λa = λc =1.here, n denotes length of the
codeword, w is the weight of the codes and λa &λc denotes auto correlation and cross correlation
constant [10]. For spectral hopping: codes from cubic congruent operator as calculated in Table 1,
from algebra theory are taken based on GF (5) and for spatial encoding codes from linear
congruent operator are taken based on GF (5) using Model B. These codes are expanded in Table

Table 4. System Parameters [6]
Simulation parameters: For 3D OCDMA system design, time delay for encoders and decoders
for variable data rate is calculated as under and is summarized in table 2.
The bit rate is taken as 1 Gbps for each channel and time slot is the length of the temporal codes.
In this simulation (13, 4, 1) OOC is taken for spreading in time domain.
Thus the bit period is calculated as:
Bit Period=1/Bit Rate =1/1e9= 1e-9 and Chip period=Bit Period/Time Slot
=1e-9/13 = .0769e-9.
Now the time delay lines for temporal code (1011000100000) [8] are calculated as
Time Delay lines for Encoder
t0 = 0×.0769e-9=0; t2=2×.0769e-9=.1538e-9
t3= 3×.0769e-9=.2307e-9; t7= 7×.0769e-9=.5384e-9
Inverse delay lines for Decoder
t13= 13×.0769e-9=.9997e-9; t11= 11×.0769e-9=.8459e-9
t10=10×.0769e-9=.7690e-9; t6=6×.0769e-9=.4614e-9](https://image.slidesharecdn.com/performanceanalysisoftransmissionof5usersbasedonmodelbusinggf5withvaryingbitratesfor3docdmasystem-131007012205-phpapp02/85/Performance-analysis-of-transmission-of-5-users-based-on-model-b-using-gf-5-with-varying-bit-rates-for-3-d-ocdma-system-4-320.jpg)

4. SIMULATION AND RESULTS
Table 4 shows the practical parameters that were taken while simulating the proposed 3D codeset
based on Model B using cubic and linear congruent operator with GF (5).Proposed System have 5
Operating wavelengths in C band i.e. λ1= 1550.0e-9m, λ2= 1550.8e-9m, λ3= 1551.6e-9m, λ4=
1552.4e-9m and λ5= 1553.2e-9m with variable repetition rate=1e9, 2e9 ,5e9 and 10e9 and peak
power= 1.0e-3 w of MLL (Laser). And Delta =.8e-9 (i.e. spacing between the wavelength) is
based on Dense Wavelength Division Multiplexing [9]. Fig 2 shows the snapshots of 3D
OCDMA, in OPTSIM Simulation Software.
This schematic evaluates the 3D OCDMA link with encoding/ decoding based on Model B with 5
users each transmitting at variable data rate coding based on Galois field GF (5) with cubic and
linear congruent operator and optical orthogonal codes.
Fig 3 through 6 shows the signal strength in terms of eye diagram, signal spectrum and auto
correlation function at 1Gbps, 2Gbps, 5Gbps and 10 Gbps data rates. These diagrams illustrate
that as the bit rate increases from 1Gbps to 10Gbps the eye diagram approaches towards close and
signal spectrum deteriorates.
The above said signals when passed to 3D OCDMA system results in successful transmission at
variable attenuation with data is given in Table 5 through 8, yellow marks in the table shows
minimum and maximum attenuation values and Figures 8 through 11 shows output signal](https://image.slidesharecdn.com/performanceanalysisoftransmissionof5usersbasedonmodelbusinggf5withvaryingbitratesfor3docdmasystem-131007012205-phpapp02/85/Performance-analysis-of-transmission-of-5-users-based-on-model-b-using-gf-5-with-varying-bit-rates-for-3-d-ocdma-system-5-320.jpg)
