    摘要： The present invention relates to a transmitting device. The transmitting device (100) comprises a processor (102), and a transmitter (104); wherein the processor (102) is configured to generate a fractional Orthogonal Frequency Division Multiplexing, OFDM, symbol based on an adjacent OFDM symbol, wherein the fractional OFDM symbol is a cyclic extension of the adjacent OFDM symbol; wherein the transmitter (104) is configured to transmit a multicarrier signal comprising the fractional OFDM symbol and the adjacent OFDM symbol. Furthermore, the present invention also relates to a corresponding method, a multicarrier wireless communication system comprising such a transmitting device, a computer program, and a computer program product.

    摘要： The present invention relates to a method for generating synchronization signals for wireless communication systems, said method comprising the steps of: defining a number sequence d
    u [n], n = 0,1,..., L— 1 of length L, said number sequence being centrally symmetric around the element n = (L— l)/2 of said number sequence, L being an odd positive integer and n denoting element index; mapping said number sequence on a first set of discrete Fourier frequency coefficients formula (I); generating a second set of discrete Fourier frequency coefficients H
    u by frequency shifting said first set of discrete Fourier frequency coefficients formula (I) by m shifts, where m is an integer except zero; and transforming said second set of discrete Fourier frequency coefficients H
    u into a time domain signal. Furthermore, the invention also relates to a computer program, a computer program product, a signal processing device, and a receiver device.
