[0028] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.
[0029] The present invention provides a method for enhancing the preamble of the existing orthogonal frequency division multiplexing system. To this end, a new preamble symbol is added to each radio frame of the original system.
[0030] In the above method for enhancing the preamble of an orthogonal frequency division multiplexing system, a new preamble symbol is sent at a position close to the original preamble symbol in the radio frame.
[0031] In the foregoing method for enhancing the preamble of an orthogonal frequency division multiplexing system, the transmit diversity mode of the new preamble symbol is the same as that of the original preamble symbol.
[0032] In the above-mentioned method for enhancing the preamble of the orthogonal frequency division multiplexing system, the new preamble symbol transmits the information of the C...
