Title:
ナビゲーション・システムのためのマルチパス・ディスクリミネータ・モジュール
Document Type and Number:
Japanese Patent JP4133808
Kind Code:
B2
Abstract:
A multipath discriminator module and related methods are provided for communications and/or navigation systems that implement spread spectrum modulation. In one example embodiment, the module includes an input suitable for receiving navigation signals, a sampler for supplying sampled signals at a frequency twice the apparent frequency of the code of the signals, and a submodule for calculating an error signal from the sampled signals.
