Abstract
A method for generating an ultra-wideband communications signal is described. The method includes generating a piecewise linear ultra-wideband baseband signal comprising at least one pulse, based on an inputted data signal; generating a carrier tone having a carrier frequency suitable for wireless transmission; and upconverting the baseband signal with the carrier tone to the carrier frequency. A method for interpreting a received ultra-wideband communications signal, the signal having a center frequency in the RF domain, is also described. The method includes generating at least one local signal template, synchronized with the received ultra-wideband communications signal and having substantially the same center frequency; correlating the received ultra-wideband communications signal with each of the local signal templates in the analog domain, obtaining at least one ultra-wideband baseband signal; and interpreting the at least one ultra-wideband baseband signal to generate a data signal. Devices for implementing these methods are also described.
