Design of Networked Wireless Transceivers Part 1: Wireless Network Modeling
From the series: Design of Networked Wireless Transceivers
Simulink® modeling of wireless networks is the first step in using Model-Based Design prototype and implementing the networks. We developed a Simulink system model for a relatively complete wireless network. The modeled wireless network uses packetized data and half-duplexing on transmission and receiving, like those employed in WLAN, IOT, and TD-LET. The model provides insight into using Simulink to simulate a wireless network. It also shows efficient implementations for some key functions in communication systems, such as a radio network with bi-directional paths, decision feedback equalizer, head/frame CRCs, and MAC layer. With this model, various system behaviors can be studied, including:
- Different channel models (mobile channel, MIMO channel, etc.)
- Selected PHY and MAC schemes (QPSK, ALOHA based, and 802.11-CSMA/CA)
- Different architectures for the function blocks in the system
- Interactions between the radio nodes in the network
This model uses HDL-supported Simulink and Stateflow® models that facilitate automatic HDL code generation of the transceiver functions. Automatic HDL code generation greatly increases the efficiency of SDR+FPGA prototyping and ASIC implementation.
