    • A wideband receiver, including a time-varying finite impulse response (FIR) filter, has been provided to combine multipath communications of data in response to pilot channel timing information. The time-varying FIR processes the multipath communications through independent signal paths. Each signal path includes a variable delay circuit and a variable gain circuit. The delay of each separate signal path is adjusted and made equal in response to the pilot channel timing information. Likewise, the gain of each signal path is adjusted in response to pilot channel gain information to maximize the signal to noise ratio of the combined signal paths. The separate signal paths are then summed in a combiner circuit. The time-varying FIR permits the data communication to be summed either before, or after demodulation. A method of combining multipath communications using a time-varying FIR is also provided.
    • 已经提供了包括时变有限脉冲响应(FIR)滤波器的宽带接收机,以响应于导频信道定时信息来组合数据的多路径通信。 时变FIR通过独立的信号路径处理多路径通信。 每个信号路径包括可变延迟电路和可变增益电路。 每个单独的信号路径的延迟被调整并且响应于导频信道定时信息使其相等。 类似地,响应于导频信道增益信息调整每个信号路径的增益,以最大化组合信号路径的信噪比。 然后将单独的信号路径在组合器电路中相加。 时变FIR允许在解调之前或之后将数据通信相加。 还提供了使用时变FIR组合多路径通信的方法。
