摘要： A preamble for an OFDM signal synchronizes (104) and estimates (106) the sub-channels with only one code. One polyphase code sequence is used repeatedly for the preamble. The preamble is spread out over the bandwidth, which is the same as an OFDM symbol in the frequency domain and has good autocorrelation characteristics in the time domain. All OFDM signals are added with this preamble at the beginning of the OFDM signal and transmitted on the channel at a transmitter (50). At the receiving end, the receiver (100) first does the autocorrelation process to find out a peak value for synchronization in the time domain. Then, since the polyphase code is known at the receiver, the signal to noise ratio for each sub-carrier is calculated in the frequency domain and smoothed using the normal (Gaussian) distribution to provide the channel estimation. Since the synchronization and channel estimation are processed with a single preamble, the overhead for these two functions is significantly reduced.

摘要翻译： OFDM信号的前导码同步（104）并仅使用一个码估计（106）子信道。 对于前同步码重复使用一个多相码序列。 前导码在带宽上扩展，与频域中的OFDM符号相同，并且在时域中具有良好的自相关特性。 所有OFDM信号在OFDM信号的开始处与该前同步码相加，并在发射机（50）的信道上发送。 在接收端，接收机（100）首先进行自相关处理，以找出在时域中同步的峰值。 然后，由于在接收机处已知多相码，所以在频域中计算每个子载波的信噪比并使用正态（高斯）分布进行平滑，以提供信道估计。 由于使用单个前同步码来处理同步和信道估计，所以这两个功能的开销显着降低。
