When complex spread spectrum signals are received, their processing is performed by a correlator or matched filter. Thanks to available modern integrated processors and low-noise ADCs, the correlation of the received signal with its copy occurs in digital form. That is, the signal is converted into digital form, after which the calculation of the correlation function is performed using an FPGA or a processor. At the same time, there are simpler ways to find the correlation peak. Modeling one of these methods - using a sliding correlator - is discussed in this article.
