- Abstract
Nonlinear signal processing techniques used in interference suppressing in DSSS communications are discussed in detail in this paper, including adaptive amplitude processing (ADP), nonlinear Volterra spreading and nonlinear signal preprocessing, etc.. And a new efficient nonlinear filter architecture is proposed. Based on nonlinear parallel processing architecture, computational efficiency can be improved to a great extent in this new filter. Theoretic analysis and simulation results prove its advantages.
