Abstract
In this paper we study the influence of phase noise from free-running local oscillators on SAGE signal parameter estimation. Phase noise is here modeled as a random-walk process. We present phase noise estimates from our LUND RUSK MIMO channel sounder, and draw conclusions on requirements on local oscillators´ phase noise in terms of the Allan variance. We investigate an error propagation effect in SAGE, and finally, we present the random-walk phase noise effect on channel capacity.
