通常，OFDM 系统使用预定义的信号模式，称为前导码 (2) (3)，这有助于接收器通过频率偏移和信道估计实现更好的信号检测（粗略、精细时间同步）。在大多数情况下，满足所有这些条件时，接收器可以获得相对良好的性能，同时保持尽可能低的总功耗和 BER（误码率）。本文介绍了将前导码 (2) (3) 的一部分与 Minn 训练序列相结合所获得的结果。我们得到了有趣的性能结果，与相对较新的标准 802.16a 获得的结果相当。
Generally OFDM systems use a predefined signal pattern, called preamble (2) (3), which helps the receiver to achieve a better signal detection (coarse, fine time synchronization) with the frequency offset and chan- nel estimation. In most of the time having all these condi- tions fulfilled the receiver achieves relatively a good performance while keeping as low as possible the total consuming power and the BER (Bite Error Rate). This paper presents the results obtained while combining a part of the preamble (2) (3) and the Minn's training sequence. We have got interesting performance results comparable to those results obtained for the relatively new standard 802.16a.
