<p>A method for receiving a pilot symbol in a single carrier frequency division multiple access, SC-FDMA, receiver (400). In a first step (806), a cyclic prefix is removed from a received sequence to produce a modified sequence (808); the modified sequence is then transformed in a second step (810) to a first frequency domain sequence according to a first transform. In a third step (812), a plurality of distributed subcarriers in the transformed modified sequence are demapped in order to extract a plurality of received pilot symbols. An intermediate channel estimate for each of the plurality of received pilot symbols is derived based on one or more characteristics of each of the plurality of pilot symbols in a further step (814). In a final step (816), interpolation is performed on the intermediate channel estimates to obtain final channel estimates.</p> |
