This is a basic implementation of a 802.11 receiver written in C without external dependencies. The purpose of this code is to provide a good opportunity to understand the different parts of the 802.11 PHY hands-on.

Supported Features

• HT-mixed/VHT 20 MHz Single Stream
• MCS 0-7

TODO

• More efficient synchronization - still too slow / buggy
• VHT-QAM256 support
• UHD integration
• legacy support (i am lazy)
• Phase offset overestimated when freq offset is high

Missing Features

• Multiple Streams
• 40/80/80+80/160 MHz support
• LDPC (Low Density Parity Coding)
• STBC (Space Time Block Coding)
