<p>A method for generating an ultra-wideband communications signal, comprising the steps of: (a) generating a piecewise linear ultra-wideband baseband signal comprising at least one pulse, based on an inputted data signal; (b) generating a carrier tone having a carrier frequency suitable for wireless transmission; and (c) upconverting the baseband signal with the carrier tone to the carrier frequency, thereby generating said ultra-wideband communications signal. A method for interpreting a received ultra-wideband communications signal, the signal having a centre frequency in the RF domain, comprising the steps of: (d) generating at least one local signal template, synchronised with said received ultra-wideband communications signal and having substantially the same centre frequency; (e) correlating said received ultra-wideband communications signal with each of the local signal templates in the analog domain, thereby obtaining at least one ultra-wideband baseband signal; and (f) interpreting said at least one ultra-wideband baseband signal to generate a data signal.</p> |
