摘要： In a multicarrier radio transmission system complex-valued symbols are assigned to at least a first subcarrier and a second adjacent subcarrier, wherein the symbols assigned to the second subcarrier are offset in frequency by half a subcarrier against the symbols assigned to the first subcarrier.

摘要： In an orthogonal multicarrier radio transmission system complex-valued symbols are transmitted, wherein the real part and the imaginary part of each symbol are shifted against each other by one half symbol period and wherein a non-symmetric conjugate-root filter is applied to each symbol before transmission to mitigate inter-carrier interference and intersymbol interference. Corresponding reverse steps are performed at the receiver.

摘要： A radio transmission system based on a frequency divisional multiplexing method is described, wherein a transmit symbol comprises a plurality of data symbols assigned to at least two subcarriers. The information of symbols of one time slot is spread across the data symbols of subcarrier of the time slot to produce a transmit symbol being more robust to frequency selective channels.
