Distribution of reference symbols in a frame

摘要

In a wireless communication technique, a frame including a training sequence and a mixed data sequence in which at least one symbol of a whitened sequence is dispersively inserted into a data sequence is generated. The frame is converted into a wireless signal, which is then transmitted. The wireless signal of the frame is received. Tap coefficients of an equalization filter are set by using the training sequence in the frame. During reception of the mixed data sequence, an adaptive operation is performed by using the respective symbols of the whitened sequence in the frame and the tap coefficients of the equalization filter are updated. To improve tracking performance of an adaptive equalizing operation while reducing the calculation volume. <IMAGE>
