Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for transmission and reception of data. SOLUTION: Various embodiments are described to provide for the transmission and reception of data in an improved manner. Data transmission includes in a transmitter a null generator (110) to generate an output data symbol sequence that exhibits nulls in the frequency domain at particular frequencies without an input data symbol sequence. A pilot inserter (120) adds a pilot symbol sequence to this output data symbol sequence to create a combined symbol sequence. Since the pilot symbol sequence exhibits pilot signals corresponding to the nulls of the output data symbol sequence in the frequency domain, the combined symbol sequence exhibits pilots that are orthogonal to the data in the frequency domain.
