Summary: 
Combining a layered space-time receiver with the OFDM for high-rate transmissions requires the multi-channel estimation process. Therefore, this letter highlights a design of a preamble structure for OFDM-based layered space-time receiver. The new proposed preamble can estimate the multi-channel up to the 8 transmit antennas using two long preambles in the WLAN standards.
