Laboratory Stand “Telecommunication Simulator”

I. Module Introduction

The experimental platform adopts a modular design and is mainly composed of standard modules and optional modules. The following introduces nine standard modules in the communication principle experimental platform to understand the specific functions and features of each module.

Standard Modules include:

1. Master & Signal Source Module
2. Digital Terminal & Time Division Multiple Access Module
3. Source Code Module
4. Channel Compilation Code Module
5. Time Division Multiplexing & Time Division Switching Module
6. Baseband Transmission Code Module
7. Digital Modulation and Demodulation Module
8. Carrier Sync and Bit Sync Module
9. PCM Code and Voice Terminal Module

The experimental platform of communication principle also includes many matching modules. Here, only the channel analog module, the software radio modulation module, the software radio demodulation module, the channel coding and interleaving module, and the channel decoding and deinterleaving module are described. Other optional modules are not introduced.
