Patent ID: 7949065

Claim:
A method for transmitting information by radio from a transmitter to a receiver, comprising: transmitting at least one first symbol of a first total length, including first useful data during a first time period and cyclic repetitions of the first useful data during a second time period; transmitting at least one second symbol of the first total length, including second useful data during a third time period, having a first length different than the first time period, and cyclic repetitions of the second useful data during a fourth time period, having a second length different than the second time period; and processing of the at least one first and at least one second symbols by at least one of the transmitter and the receiver at a first sampling rate of the first useful data transmitted during the first time period different from a second sampling rate of the second useful data transmitted during the third time period, where a number of samples of the first useful data transmitted during the first time period is equal to the number of the samples of the second useful data transmitted during the third time period.
