Description
Summary:The article is devoted to solving the problem of implementing a spatial filtering algorithm using the least squares method on a programmable integrated circuit. The necessity of using special signal processing methods is explained by the presence of a complex interference environment and a low signal level from the satellite at the receiving point during the operation of global navigation satellite systems. The algorithm under consideration is effectively used in a stationary signal-to-noise environment and is the simplest adaptive algorithm in terms of computational complexity. A comparison is made between the theoretical model of an adaptive processing algorithm and experimental data obtained during implementation on a programmable logic circuit.
