Hi  sir

           I have some confusion in AoA sample,

          1， in AoA_getPairAngles(), why Zre and Zim need  >>= 10?,  and why the angle result is 256/2*pi?

          2,  in AoAReceiver_estimageAngle(), why  AoA_A1 need +45 and AoA_A2 need  -45?

  const int16_t AoA_A1 = ((AoAReceiver_antA1Result->pairAngle[0] + AoAReceiver_antA1Result->pairAngle[1]) / 2) + 45 + AoA_A1_freqComp;
  const int16_t AoA_A2 = ((AoAReceiver_antA2Result->pairAngle[0] + AoAReceiver_antA2Result->pairAngle[1]) / 2) - 45 - AoA_A2_freqComp;

           3,Actually I can`t imagine how to get the Angle of the signal  coming into the antennas, can you show me a diagram of the signal coming into different antennas, and by these angles of different antennas, how to calculate the acturally angle of arrive.
