This adaptive channel tracking method can overcome deep attenuation and AWGN noises effectively due to several blocks of symbol are considered simultaneously.
这种方法由于在信道跟踪时，同时利用了多个块符号的信息，可以有效克服噪声和深衰落的影响。

Even in the badly wireless channel environment the proposed tracking method can track considerable blocks of symbol and there is no need for channel acquisition again.
即使在恶劣的无线移动信道下，该跟踪方法仍然能够跟踪相当长信息符号块而无需重新捕获。

A new blind symbol timing-tracking algorithm is proposed, using the special OFDM frame structure with cyclic prefix and cyclic postfix.
