Abstract
Spatial pilot supporting MIMO receiver in multi-antenna multi-layer transmission communication system. For single layer transmission, the first layer pilot is repeated across the subbands of the first OFDM symbol, and the first layer pilot is repeated in the adjacent second OFDM symbol with an offset from the first OFDM symbol. . Additional transmission layers may be transmitted, each with a separate pilot generated and repeated in the first symbol, and further repeated in the adjacent second symbol offset from each other. Thereafter, the first and second OFDM symbols are transmitted and received to determine the characteristics of the reception channel.
