    • An OFDM receiver receives OFDM symbols in the frequency domain and comb filters and then punctures the OFDM symbols to leave symbols with actual pilot information and with null values at the data symbols. The receiver provides the punctured OFDM symbols to an OFDM symbol queue. A virtual pilot interpolator is coupled to the punctured OFDM symbol storage to generate virtual pilot information introduced to OFDM symbols. The interpolator may be a two dimensional Wiener filter. The receiver also includes a time domain channel estimator that processes a first OFDM symbol including virtual pilot information to generate a channel impulse response for the first OFDM symbol. A frequency equalizer equalizes the OFDM symbol in response to the channel impulse response for the first OFDM symbol.

    • An OFDM communication system performs time domain channel estimation responsive to received symbols before the symbols are processed by a fast Fourier transform. The communication system generates virtual pilots from actual pilots to improve the stability and quality of channel estimation. The system generates a reference signal from the actual and virtual pilots and correlates the resulting reference signal with a signal responsive to the received symbol to generate an initial channel impulse response (CIR) and to determine statistics about the channel. In some circumstances, the resulting reference signal is correlated with a modified symbol in which the actual and virtual pilot locations are emphasized and the data locations are deemphasized. Time domain channel estimation iteratively improves on the initial CIR. The system determines channel estimates for data only symbols through averaging such as interpolation.
    • 在通过快速傅里叶变换处理符号之前,OFDM通信系统响应于接收的符号执行时域信道估计。 通信系统从实际导频生成虚拟导频,提高信道估计的稳定性和质量。 该系统从实际和虚拟导频生成参考信号,并使得到的参考信号与响应于接收到的符号的信号相关,以产生初始信道脉冲响应(CIR)并且确定关于信道的统计。 在一些情况下,所得到的参考信号与其中强调实际和虚拟导频位置并且数据位置被加重的修改符号相关。 时域信道估计在初始CIR上迭代地提高。 该系统通过诸如插值的平均来确定仅数据符号的信道估计。

The system may include a number of object entrance ports, object exit ports, elevators, horizontal transportation systems, and storage levels, each storage level including a number storage bays. The horizontal transportation systems may move objects after they have been mounted on frames.

    • An OFDM system generates a channel estimate in the time domain for use in either a frequency domain equalizer or in a time domain equalizer. Preferably channel estimation is accomplished in the time domain using a locally generated reference signal. The channel estimator generates an initial estimate from a cross correlation between the time domain reference signal and an input signal input to the receiver and generates at least one successive channel estimate. Preferably the successive channel estimate is determined by vector addition (or subtraction) to the initial channel estimate. The at least one successive channel estimate reduces the minimum mean square error of the estimate with respect to a received signal.
    • OFDM系统在时域中产生用于频域均衡器或时域均衡器中的信道估计。 优选地,使用本地生成的参考信号在时域中完成信道估计。 信道估计器根据时域参考信号和输入到接收机的输入信号之间的互相关产生初始估计,并产生至少一个连续的信道估计。 优选地,通过对初始信道估计的向量相加(或减法)来确定连续信道估计。 所述至少一个连续的信道估计相对于接收到的信号减小估计的最小均方误差。
