in [communication systems](https://en.wikipedia.org/wiki/Communications_system#:~:text=A%20communications%20system%20or%20communication,to%20form%20an%20integrated%20whole.).Line coding is a process of converting [digital data](https://en.wikipedia.org/wiki/Digital_data#:~:text=Digital%20data%2C%20in%20information%20theory,a%20string%20of%20alphanumeric%20characters.) to [digital signals](https://en.wikipedia.org/wiki/Digital_signal).\n   This repository is structured into three main categories: 'Bipolar', 'Polar', and 'Unipolar', each containing methods for 'Non-Return-to-Zero (NRZ)' and 'Return-to-Zero (RZ)' coding.\n\n\n## Line Coding Techniques\n\n   * [Bipolar Line Coding](Bipolar)\n\n      1. Bipolar NRZ:\n         - The signal level alternates between positive and negative values for successive 1s.\n         - Zero level for 0s.\n         - More efficient use of bandwidth compared to unipolar line coding.\n\n      2. Bipolar RZ:\n         - Similar to Bipolar NRZ but returns to zero between each bit.\n         - Provides a clearer timing for synchronization but requires more bandwidth.\n\n\n   * [Polar Line Coding](Polar)\n\n      1. Polar NRZ:\n         - Uses two levels of voltage, positive and negative, to represent binary 1 and 0.\n         - Does not return to zero between bits, thus more bandwidth efficient.\n\n      2. Polar RZ:\n         - Similar to Polar NRZ but returns to zero between each bit.\n         - Easier to synchronize but requires more bandwidth.\n\n\n   * [Unipolar Line Coding](Unipolar)\n\n      1. Unipolar NRZ:\n         - Uses a single non-zero voltage level to represent binary 1.\n         - Zero voltage level represents binary 0.\n         - Simplest form of line coding but can have DC component issues.\n\n      2. Unipolar RZ:\n         - Similar to Unipolar NRZ but returns to zero between each bit.\n         - Easier to synchronize but requires more bandwidth.\n\n## Repository Structure\n\n   The repository is organized into the following directories and files:\n\n   - Bipolar\n\n       - [Bipolar_RZ.ipynb:](Bipolar/Bipolar_RZ.ipynb) Implementation of Bipolar Return-to-Zero (RZ) line coding.\n       - [Bipolar_NRZ.ipynb:](Bipolar/Bipolar_NRZ.ipynb) Implementation of Bipolar Non-Return-to-Zero (NRZ) line coding.\n\n\n   - Polar\n\n       - [Polar_RZ.ipynb:](Polar/Polar_RZ.ipynb) Implementation of Polar Return-to-Zero (RZ) line coding.\n       - [Polar_NRZ.ipynb:](Polar/Polar_NRZ.ipynb) Implementation of Polar Non-Return-to-Zero (NRZ) line coding.\n\n\n   - Unipolar\n\n       - [UNPolar_RZ.ipynb:](Unipolar/UNPolar_RZ.ipynb.ipynb) Implementation of Unipolar Return-to-Zero (RZ) line coding.\n       - [UNPolar_NRZ.ipynb:](Unipolar/UNPolar_NRZ.ipynb) Implementation of Unipolar Non-Return-to-Zero (NRZ) line coding.\n    \n\n## References\n\n   * The concepts and explanations of the following article are used:\n\n\n      * [Line Codes for Communication Systems - Original Paper](Line%20Codes%20for%20Communication%20Systems.pdf)\n\n\n   * BOOK:\n\n      * [Computer Network Tanenbaum](Computer%20Network%20Tanenbaum.pdf): This book has been used to teach the concepts of communication systems.\n\n\n   * You can also refer to the following file to know the performance of each of the implemented methods:\n\n\n      * [Line Coding](Line%20Coding.pdf)\n\n## License\n\n   This repository is licensed under the MIT License.\n   See the [LICENSE](./LICENSE) file for more details.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjelhamm%2Fline-codes-for-communication-systems","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjelhamm%2Fline-codes-for-communication-systems","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjelhamm%2Fline-codes-for-communication-systems/lists"}
