Optimization of Advanced Signal Processing Architectures for Detection of Signals Immersed in Noise

Abstract

The use of Field Programmable Gate Array (FPGA) devices in the signal processing field has been on a constant rise since the beginning of the last decade. In particular, in the field of signal processing applications, the implementation of methods and techniques for the detection of coded signals immersed in noise should be highlighted. In this chapter, focus is placed on a special type of coding known as Complementary Sequences, and on some of the coding schemes derived from them. These sequences have been employed in many different application fields, ranging from safety sensors and radar systems to communications and material characterization. Specifically, this chapter deals with issues related to algorithms improvement and to their implementation in FPGA platforms, with particular emphasis on hardware resources efficiency and on the reliability of the whole processing scheme.
