Abstract:
1. A method for generating a multiple band ultrawide bandwidth signal, comprising: providing a first reference signal having a first reference frequency; multiplying the first reference signal by M to generate a second reference signal having a second reference frequency that is M times the first reference frequency; selecting one of the first reference signal and the second reference signal as a selected reference signal having a selected reference frequency; dividing the selected reference signal by L to generate a bit rate clock; receiving a plurality of data bits based on the bit rate clock; and generating an ultrawide bandwidth signal at a transmitter circuit based on the selected reference signal and one of the plurality of data bits, the ultrawide bandwidth signal including two or more pulses having the selected reference frequency, wherein M is an integer greater than 1, and wherein L is an integer greater than 1.
