FPGA Implementation of an Efficient Correlator for Complementary Sets of Sequences

The use of complementary sets of sequences is especially relevant in multisensorial systems, with simultaneous emissions from different sources and low signal-to-noise ratio (SNR). There exist efficient generation and correlation algorithms that give a reduction in the computational load and complexity of a hardware implementation. In this work a new hardware design approach for an efficient correlator of complementary sets of sequences (CCS) is presented. It is based on utilising reconfigurable logic to gain the required flexibility in terms of correlator parameters. The configuration of the design is carried out at the pre-synthesis stage, so the user can change this configuration according to the requirements of the application
