A Simplified Training Pattern for MIMO-OFDM Channel Estimation Technology
The tracking of fading wireless channel is needed in MIMO-OFDM system. Training sequences can be used for synchronization and channel estimation. However, if too much training blocks are used, the efficiency of system will be decreased. A simplified training pattern which can reduce the waste of resources is proposed in this paper. Computer simulations prove that performance of the system with simplified pattern is almost equivalent to the system doesnt use the simplified training pattern under low SNR, with SNR rising, the performance of the system with simplified training block pattern will become better and better, and the simplified pattern can save four OFDM periods for transmitting training blocks.
