Efficient pseudo-noise sequence generation for spread-spectrum applications

Novel approaches for linear feedback shift register based pseudo noise generators are presented. Area-delay tradeoff between the various approaches is also presented. The principal approaches that are studied in this paper include 1) State-transition matrix based approaches, 2) State-transition matrix based approaches with lookahead, 3) State storage based approaches and 4) Polynomial multiplication based approaches. Synthesis results are also provided to illustrate the area/delay trade-offs.
