Abstract
A receiver circuit comprising an averaging-processing-block that is configured to receive an OFDM signal. The OFDM signal comprises a plurality of sample-values, wherein the sample-values comprise: a middle-sample-value; a lower-sample-value-group; and a higher-sample-value-group. The averaging-processing-block can determine an averaged-sample-value for the middle-sample-value by performing an averaging operation on the sample-values of the lower-sample-value-group and the higher-sample-value-group, but not on the middle-sample-value.

A receiver circuit comprising:
- an Orthogonal Frequency Division Multiplexing (OFDM) receiver configured to receive an OFDM signal that comprises a plurality of sample-values, wherein the plurality of sample-values comprise a middle-sample-value, a lower-sample-value-group received earlier in time than the middle-sample-value, a higher-sample-value-group received later in time than the middle-sample-value, and determine an averaged-sample-value for the middle-sample-value by performing an extrinsic information averaging operation on the sample-values of the lower-sample-value-group and the higher-sample-value-group, but not on the middle-sample-value.
A method of processing an OFDM signal, wherein the OFDM signal comprises a plurality of sample-values, wherein the sample-values comprise:
- a middle-sample-value, a lower-sample-value-group received earlier in time than the middle-sample-value, and a higher-sample-value-group received later in time than the middle-sample-value, the method comprising:
- determining an averaged-sample-value for the middle-sample-value by performing an extrinsic information averaging operation on the sample-values of the lower-sample-value-group and the higher-sample-value-group, but not on the middle-sample-value;
- and
- using the averaged-sample-value for at least one of demodulation and decoding of the OFDM signal.
