| description | This paper proposes a preamble structure that raises the throughput of the physical layer of a MIMO-OFDM system that complies with I II 802.11n. The proposed preamble is based on two important criteria that have not been considered in conventional preamble structures but have an important bearing on realization of I II 802.11n. One is backward compatibility with legacy devices, such as I II 802.11a or I II 802.11g. The other is accurate AGC for MIMO data payload of the packet. Computer simulations and a laboratory test demonstrate that the proposed preamble is superior to the other preambles with respect to those two important criteria. The results were submitted to the task group N under the I II 802.11 working group and contributed to development of the current draft of I II 802.11n. |
