|
========
|
|
|
|
This project contains a Verilog implementation of 802.11 OFDM PHY decoder.
|
|
Features are:
|
|
|
|
- Fully synthesizable (tested on Ettus Research USRP N210 platform)
|
|
- Full support for legacy 802.11a/g
|
|
- Support 802.11n for MCS 0 - 7 @ 20 MHz bandwidth
|
|
- Cross validation with included Python decoder
|
|
- Modular design for easy modification and extension
|
|
|
|
|
|
Environment Setup
|
|
-----------------
|
|
|
|
This project has the following dependencies:
|
|
|
|
- `Icarus Verilog <http://iverilog.icarus.com/>`_: for compiling Verilog files and simulation.
|
|
- `GtkWave <http://iverilog.icarus.com/>`_: for wave form visualization.
|
|
|
|
|
|
Input and Output
|
|
----------------
|
|
|
|
In a nutshell, the top level ``dot11`` Verilog module takes 32-bit I/Q samples
|
|
(16-bit each) as input, and output decoded bytes in 802.11 packet. The sampling
|
|
rate is 20 MSPS and the clock rate is 100 MHz. This means this module expects
|
|
one pair of I/Q sample every 5 clock ticks.
