Abstract

A method and apparatus for receiving and converting spread spectrum signals is disclosed. The method and apparatus allow the receiving of spread spectrum signals and different frequency bands substantially simultaneously on the same chain of hardware components. The received signals are processed on the chain of hardware components and the resulting signal thereafter can further be used within an electronic circuit. The method includes the steps of converting analog signals into a lower frequency digital signal. The conversion step includes capturing a plurality of incoming signals within a predetermined spectral range, filtering out of the incoming signals a first plurality of analog spread spectrum signals in a plurality of analog spread spectrum signals in a plurality of predetermined bands with predetermined widths, and sampling the analog signals with a sampling frequency F.sub.s wherein F.sub.s is chosen such that the resulting time-discreet signal comprises a second plurality of analog spread spectrum signals, being the first plurality of analog spread spectrum signals which have been aliased without substantial self-aliasing.
