Figure 6From: Throughput enhancement using synchronization and three-dimensional resource allocationThe 2D structure of MASs in the conventional MB-OFDM. The number of assigned MASs when r1 = 6 is 8 with I 2 ( m 2 = 16 ) . In this example, the available MASs in I 1 are insufficient (m1 = 4). Hence, the assignment for I 2 is needed, and two MASs are excessively allocated.Back to article page
