Abstract:
In a wireless communication system, interference on data tones is estimated by detecting data transmissions from interferers. An overall interference covariance matrix is estimated as a function of scalar traffic to pilot ratio (TPR) estimates, residual interference covariance estimates, and covariance of channel estimates of dominant interferers. The interference estimates are refined as a function of reliability based on a ratio of power received from a serving cell and power received from a dominant interferer.
