摘要
current system of 802.11a and backward compatible for MIMO-OFDM system with a (low) the overhead long (long) and the preamble channel estimator is provided . The preamble includes a second training sequence including a phase shift of the first training sequence and the first training sequence. The first training sequence comprises a training sequence 802.11a . The preamble may include multiple training sequence , wherein the training sequence values each different mobile phase of the first training sequence .
