Method and apparatus for communication channel estimation

A receiver circuit configured to determine channel estimates for non-received signal frequencies, said receiver circuit comprising one or more processing circuits configured to:

• determine a plurality of channel frequency responses for a plurality of received signal frequencies;
• calculate autoregression coefficients for an autoregression model using the plurality of channel frequency responses;
• predict channel frequency responses for one or more non-received signal frequencies using the autoregression model;

A method of assigning subsets of OFOM data sub carriers to respective ones in a plurality of wireless communication receivers comprising:

• for each wireless communication receiver, measuring channel estimates for OFOM sub carrier frequencies currently assigned to the wireless communication receiver, and predicting channel estimates for OFDM sub carrier frequencies not currently assigned to the wireless communication receiver via autoregression modeling based on the measured channel estimates;
• jointly evaluating measured and predicted channel estimates for the wireless communication receivers;
• and
• assigning particular OFDM data sub carriers to particular wireless communication receivers based on said joint evaluation.
