Active Ports Per Allocation (Custom OFDM)
Menu Path:
This property is only valid when Resource Interface = Type2.
Active Ports Per Allocation is an array describing the active port associated with each allocation ID, as listed in the Resource Allocations mapping array.
This property is an array of integer bitmap values, with one bitmap value for each allocation ID, as listed in the Resource Allocations mapping array. The values are unitless. The active ports bitmap value can be used to determine the arbitrary subset of active ports (0..Transmitter Antennas-1) to which each allocation ID maps. For example: if bit0 is true, port 0 is active for this allocation; If bit1 is true, port 1 is active for this allocation; etc. If this array is shorter than the highest allocation ID, any values past the end are assumed to be 0.
