| Popis: | Blind signal search is a technique used in many different types of systems, ranging from cognitive radio to broadcasting applications such as television and radio. A well-known approach used for this, is the Cyclostationary Feature Detection algorithm, which can estimate the baud rate of a detected signal, but is not capable of identifying its position in the spectrum, nor properly analyse spans with more than one signal. This paper introduces an algorithm that enables Cyclostationary Feature Detection to overcome these two limitations and presents its circuit implementation that uses one single filter to operate. Such circuit, designed for ASIC, was prototyped on FPGA and tested using signals generated in laboratory, as well as, real signals captured from a commercial satellite, proving its effectiveness. |
