In a FSS-OFDMA, the OFDM symbol is spread, and the subcarriers are assigned for each user in the frequency band. As the principal subcarrier allocation for each user, localized and interleaved allocations have been proposed, and the interleaved allocation is improved for the BER performance to avoid continuous deep faded subcarrier channels. Also, in the independent channel fluctuation for each user, the MUDiv gain is obtained by the individual and block subcarrier allocations. However, they have a trade-off problem between the BER performance and the computational complexity. To solve this problem, the interleaved block subcarrier allocation has been proposed. On the other hand, the interleaved block is only evaluated for the individual subcarrier and is not evaluated for the several subcarriers. Moreover, the power combination between the subcarrier and the channel is also improved for the BER performance, but the individual and block subcarrier allocations are only evaluated. Therefore, in this paper, we propose the interleaved block subcarrier allocation and the power combination for a FSS-MUDiv/OFDMA.

在FSS-OFDMA中，OFDM符号被扩展，并且子载波被分配给频带中的每个用户。作为每个用户的主要子载波分配，已经提出了局部和交织分配，并且针对BER性能改进了交织分配，以避免连续的深度衰落子载波信道。此外，在每个用户的独立信道波动中，MUDiv 增益是通过单独和块子载波分配获得的。然而，它们在 BER 性能和计算复杂度之间存在权衡问题。为了解决这个问题，已经提出了交错块子载波分配。另一方面，交织块仅针对单个子载波进行评估，而不针对几个子载波进行评估。而且，对于 BER 性能，子载波和信道之间的功率组合也得到了改进，但仅评估了单个子载波和块子载波的分配。因此，在本文中，我们提出了 FSS-MUDiv/OFDMA 的交错块子载波分配和功率组合。
