Question: write about Optical Code Division Multiple Access. Introduction and overview, historical background, explanation of the technique, comparison between FDMA, TDMA and OCDMA, explain more on OCDMA, how does it work, why using OCDMA, advantages, what other techniques available other than OCDMA, compare them with OCDMA.
Introduction
OCDMA is a multiple access technique originating from DS-SS (Direct Sequence Spread Spectrum) and it was originally used for military purposes to ensure that transmission of information I kept safe. It is currently used in wireless communication such as mobile devices.
Overview
Here we are going to look at the OCDMA technique, how it works, its origin or background, its advantages and compare it with other techniques.
History
It started in 1941 when George Antheil and Hedy Lamar patented Spectrum communication but it was not implemented then. CDMA was later considered in the late 70’s for cellular mobiles. During this period, CDMA technology was being used for military communications to ensure that there is security in information transmission. It is now a very important technology widely used in wireless communication as 3G/4G Technology.
Explanation of the Technique
OCDMA is a technique which employs high speed transmission, exchange of data using optical signal processing to realize an all optical communication and networking. Users access the network randomly. It uses a tell-to –go protocol and can support different bitrate traffic. It transmits encrypted information making it secure
Comparison between FDMA, TDMA and OCDMA
OCDMA is different and advantageous as compared to FDMA and TDMA in that it ensures there is proper use of communication media by giving asynchronous access to every user. In OCDMA technique new users are added to the network with ease because it does not require any scheduling. OCDMA has been known to experience problems as it
