Broadband interference excision for software-radio spread-spectrum communications using time-frequency distribution synthesis.

A new method is introduced for interference excision in spread-spectrum communications that is conducive to software-radio applications. Spare processing capacity in the receiver permits the use of time-frequency techniques to synthesize a nonstationary interference from the time-frequency domain us...
