 1 | ##Introduction
 2 | This is a hackrf fm/am transreceiver(only transfer part finish for now)
 3 | 
 4 | Transfer part is inspired by <https://github.com/jocover/foo_hackrf>.
 5 | 
 6 | Receiver part is inspired by <https://github.com/kit-cel/gr-lte> and <http://www.hackrf.net/2014/04/lte-hackrf/>.
 7 | 
 8 | And on branch static, i've made a simple multi-core optimizing.
