Integrating UHD and fpga files into one directory

Based on copy block - Bypassing input into output

Intro

This repo genrate from UHD-RFNOC toolchains. This RFNOC block is create to demodulate QPSK signals to rawdata in FPGA in order to speed up QPSK bitrate.

The UHD-RFNOC toolchains use the ersion 3.14. There are some bugs in the build scripts for the E31x series USRP(the others not test).

Source tree

The most things is generated by toolchains automatically. The most important folders will list:

  • rfnoc/fpga-src
  • sim

The tested bitrate is 1.6Mbps. But the block require a higher SNR and have a high error rate. Maybe this caused by bit_sync.

The src located at rfnoc/fpga-src/
