Abstract :
The effect of local oscillator (LO) phase noise of an ultra-wide band (UWB) receiver on the detection of a nearby WiMAX receiver is investigated. An expression for the spectrum broadening effect due to the phase noise is derived, and a practical method is presented to estimate the in-band interference due to the phase noise interaction with an interfering adjacent channel signal.
