In pulse position modulation, the amplitude and width of the pulses are kept constant, while the position of each pulse with reference to position of reference pulse, is changed according to the ...

UWB (ultrawideband) differs from other RF technologies in that, instead of using a narrowband frequency carrier to transmit data, it sends pulses of energy across a spectrum of frequencies (Figure 1).

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
