... discrete set of {1, -1} is multiplied to assign positive or negative sign to the offset angles. Since the offset is an overall shift of the PAS in one drop, it should be not ed that the offset angle ... m inthesamelinkshouldbeshiftedwiththe same offset angle (all the AoD of the paths have the same offset ). The generation of all the other parameters can be the same as the original IMT...
