A method and arrangement for the combined measurement of the start of a data block and of the comprises in a more carrier transmission system for irregular transmission of data blocks

摘要

The invention relates to a method and a device for determining in a receiver both the beginning of the first symbol and carrier frequency shift during a single reception of a multicarrier signal consisting of a sequence of data signals forming a data block. Determination of the beginning of the symbol regulates the clock rate for demodulation of individual symbols. The estimated carrier frequency shift value is used as an adjustable variable for frequency correction in the receiver during reception and subsequent transmission of data signals. A test signal design rule is specified, enabling combined estimation of the beginning of the first data symbol and carrier frequency shift between the transmitter and the receiver.
