Implementation of a GNSS Receiver Signal Tracking Module

Software defined radio-based GNSS receivers are getting more and more popular. Signal tracking is the most time-consuming part of signal processing in such receivers. The main purpose was to design FPGA-based signal tracking module of a System-on-Chip-based receiver. Its hardware processor system is used for signal acquisition and position computation, while the FPGA part is used for signal tracking. The design includes data buffers with shared memory, resource-efficient signal multipliers, set of correlators, discriminators and special multichannel memory-based C/A code generator. All the units are implemented using System Verilog hardware description language.
