<P>PROBLEM TO BE SOLVED: To provide techniques to perform channel estimation using pilot weighting. <P>SOLUTION: A receiver receives at least one transmission symbol for one transmitted pilot. Each transmission symbol is generated using a single-carrier multiplexing scheme (e.g., IFDMA or LFDMA) or a multi-carrier multiplexing scheme (e.g., OFDMA). An interference estimate is derived on the basis of received pilot values obtained by processing the respective received transmission symbols, and the reliability of the received pilot values is estimated based on the interference estimate. Weights for the received pilot values are estimated on the basis of the transmitted pilot values, the estimated reliability of the received pilot values, and/or other information. A channel estimate is derived on the basis of the received pilot values and the weights. Thereafter, data detection (e.g., equalization) is executed on received data values using the channel estimate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
