A method for transmitting a single carrier wireless communication signal, said communication signal comprising a temporal frame structure, said method comprising:
- forming frames of said frame structure,
- a frame of said frame structure comprising a guard interval and a data frame,
- the guard interval comprising at least two binary sequences with characteristics of a maximum length sequence,
- at least two of said at least two binary sequences being different than each other, and
- a remaining part of said guard interval being situated before and/or after said at least two binary sequences, said remaining part comprising a sequence of zeros;
- and
- transmitting the frames via a transmitter.
A transmitter unit operable to transmit a single carrier wireless communication signal, said communication signal comprising a temporal frame structure, said transmitter unit comprising:
- a frame forming device configured to form frames of said frame structure,
- a frame of said frame structure comprising a guard interval and a data frame,
- the guard interval comprising at least two binary sequences with characteristics of a maximum length sequence,
- at least two of said at least two binary sequences being different than each other, and
- a remaining part of said guard interval being situated before and/or after said at least two binary sequences, said remaining part comprising a sequence of zeros;
- and
- a transmitter configured to transmit said frames.
A method for processing a received single carrier wireless communication signal, said communication signal comprising a temporal frame structure, said frame structure being operable to provide data management, said method comprising:
- receiving said communication signal comprising said frame structure via a receiver,
- a frame of said frame structure comprising a guard interval and a data frame,
- the guard interval comprising at least two binary sequences with characteristics of a maximum length sequence,
- at least two of said at least two binary sequences being different than each other, and
- a remaining part of said guard interval being situated before and/or after said at least two binary sequences, said remaining part comprising a sequence of zeros;
- correlating at least a part of said at least two binary sequences of the guard interval with at least one predetermined binary sequence;
- and
- outputting a correlation function.
A receiver unit operable to process a received single carrier wireless communication signal, said communication signal comprising a temporal frame structure, said frame structure being operable to provide data management, said receiver unit comprising:
- a receiver configured to receive said communication signal comprising said frame structure,
- a frame of said frame structure comprising a guard interval and a data frame,
- the guard interval comprising at least two binary sequences with characteristics of a maximum length sequence,
- at least two of said at least two binary sequences being different than each other, and
- a remaining part of said guard interval being situated before and/or after said at least two binary sequences, said remaining part comprising a sequence of zeros;
- and
- a correlation device configured to correlate at least a part of said at least two binary sequences of the guard interval with at least one predetermined binary sequence and to output a correlation function.
