GNU Radio Angle of arrival estimation with USRP

GNU Radio package implementing MUSIC and root MUSIC angle of arrival algorithms with blocks necessary to provide phase synchronization of USRP devices. Implemented blocks include:

1. MUSIC Linear Array
2. Root-MUSIC
3. Calculate Phase Difference
4. Shift Phase
5. Correlate
6. Precise Moving Average
7. Head with Reset
