Fecha de publicación: 20/02/1992 Fuente: WIPO "pollen" Apparatus and method for encoding and decoding spread spectrum signals are disclosed. The analog spread spectrum signal is received on a signal bus (52), fed into delay lines (53, 55, 57), and then fed into analog-to-digital converters (73, 75, 77). The outputs of the analog-to-digital converters (73, 75, 77) is fed into shift registers (54, 56, 58). The shifting is synchronized to a clock (66) which is under the control of a controller (64). Then, the contents of the shift registers (54, 56, 58) are cross-correlated with the contents of the wavelet sequence memory (62) in a correlation generator (60).
