Figure 7

The pilot patterns used for the investigated block allocations that use combinations of a basic block of 4 subcarriers by-3-OFDM-symbols, with one pilot and 11 payload symbols (i. e., pilot overhead ): B-IFDMA (, ), (, ), (, ), (, ), IFDMA (, ), and LFDMA (, ). Time axis is horizontal and frequency axis is vertical in this figure. The pilot positions within blocks have been determined by global optimization of the channel estimation performance of the Block-LSE (Wiener) method, and they differ from those specified for uplinks in [4, 5].
