Channel Estimation for Block-IFDMA
In this paper, pilot multiplexing and channel estimation is investigated for two different signal models of DFT precoded OFDMA with block-interleaved subcarrier allocation (B-IFDMA). The influence of the B-IFDMA signal model on the bit error rate performance with and without perfect channel knowledge is presented. Moreover, the Peak-to-Average Power Ratio of the transmit signal, as well as the pilot symbol overhead required for channel estimation is given for the two signal models.
