1.The principal of wavelet denoising is introduced and the replicability of GPS multipath effect in dynamic environment is discussed firstly.
介绍了小波滤波去噪的原理并讨论在动态环境下GPS多路径效应的重复性问题。
2.OFDM (Orthogonal Frequency Division Multiplexing) is a method that can combat multipaths, fully use the frequency band and has high data rate, and has a promising future in UWA communication.
