Fpga Realization of Time-frequency Distribution with Complex-lag Argument
نویسندگان
چکیده
Due to its ability to provide good concentration in the time-frequency plane, the fourth order complex-lag time-frequency distribution has been used for the analysis of signals with highly non-stationary instantaneous frequency. In order to make it available for practical applications, an architecture for realization of this distribution is proposed. The FPGA implementation is provided as well. Apart from the real-time processing, the proposed hardware realization is used to solve the problem of calculation errors that may appear due to the limited software precision.
