Classification and Recognition of Frequency Modulation Interference in DSSS Based on Matching Pursuits

An approach to the classification and recognition of frequency modulation interference in DSSS based on matching pursuits is proposed through establishing the dictionaries with multiple time-frequency structures.The simulation results show that the frequency modulation interferences with different time-frequency structures are classified and recognized effectively using this approach without need of pre-training.The complexity of algorithm is reduced and the real time performance is enhanced also.
