Abstract :
The time-frequency interleave (TFI) diversity method for single carrier block transmission with frequency domain equalization (SC-FDE) has been proposed. For single antenna wireless communication systems, it can provide frequency diversity in frequency selective channels by interleaving and retransmitting. In this article, the linear minimum mean square error (LMMSE) frequency domain equalization structure of TFI block transmission is presented and each diversity branch can be combined with maximum ratio. The diversity gain and bit error rate (BER) performance are analyzed in a theoretical way. Both theoretical analysis and simulation results show that for TFI block transmission with LMMSE FDE, full diversity gain can be obtained. Compared to another full diversity achieving scheme direct sequence spread spectrum (DSSS), a better BER performance can be obtained.
