Abstract
The spread spectrum communications utilizes transmission bandwidth which has potential higher than the desired signal bandwidth. Optical fibers are broadly used in fiber-optic communications, as it affirms transmission over longer distances than other forms of communication. So O-CDMA has become encouraging applicant for communications, due to its: fairness, flexibility, simplified network control and management and increased security. After going through so many researches, in this paper, we discuss how the network performance can be improved using PN sequence code, Walsh Hadamard code and Padded codes and will compare their results by knowing signal to noise ratio (SNR) v/s Bit error rate (BER) graphs, which one is more effective based on their BER v/s number of users plot and which code will be more useful to enhance the network capacity.
