Radio transmission with variable length of guard interval
Abstract:
Information, in particular OFDM-symbols, is transmitted via radio from an emitting unit to a receiving unit. At least one first symbol has a first total length, which includes a first time section during which first user data is transmitted and a second time section during which cyclic repetitions of the first user data are transmitted. Also, at least one second symbol has the first total length which includes a third time section, having a length different than the first time section, during which second user data is transmitted, and a fourth time section, having a length different than the second time section, during which cyclic repetitions of the second user data is transmitted.
