Phase noise effects on the precision of wideband mobile radio channel sounding methods

In this work three wideband mobile radio channel sounding methods are simulated and compared using computational tools. The sounders are based on OFDM, Matched Filter and STDCC methods, and different values for the level of the phase noise introduced by the receiver local oscillator are compared. The impact of this oscillator imperfection is analyzed by comparing the estimated channel results with the simulated reference channel. Other impairments factors like thermal noise or nonlinear distortion affecting the system are not considered.
