AOA From IQ samples

Hi R.M

From the given document, we can calculate phase difference from IQ samples like this:

                      antenna_versus_avg[a][b] += Pab_rel + ((Paa_rel * abs(a-b)) / numAnt);

Whether it's equal to the formula below:

                      antenna_versus_avg[b][a] += Pba_rel + ((Pbb_rel * abs(a-b)) / numAnt);
                      antenna_versus_avg[a][b] = -antenna_versus_avg[b][a]

PS:we use version 2.3 SDK , and only enable antenna 1.1, 1.2 and 1.3

Besides, is it correct that we set numAnt=3 ?
