1. A method of transmitting a pilot sequence in a broadcasting communication system, the method comprising:
- determining seed values for Orthogonal Frequency Division Multiplexing (OFDM) symbols;
generating pilot sequences including information related to an OFDM symbol index by applying a Zadoff-Chu sequence to each of the seed values;
inserting the pilot sequences into a determined subcarrier position in a frame according to a pilot pattern; and
transmitting the frame.

Abstract
A method and an apparatus for transmitting and receiving a pilot sequence in an Single Carrier-Orthogonal Frequency Division Multiplexing (SC-OFDM) scheme of a broadcasting communication system. The method includes determining seed values for Orthogonal Frequency Division Multiplexing (OFDM) symbols; generating pilot sequences including information related to an OFDM symbol index by applying a Zadoff-Chu sequence to each of the seed values; inserting the pilot sequences into a determined subcarrier position in a frame according to a pilot pattern; and transmitting the frame.

6. A method of receiving a pilot sequence in a broadcasting communication system, the method comprising:
-
detecting a position of a pilot subcarrier in a received frame, by comparing sizes of the pilot subcarrier and a data subcarrier included in a received frame; identifying a pilot sequence corresponding to the position of the pilot subcarrier; detecting a seed value from the pilot sequence; and detecting information related to an Orthogonal Frequency Division Multiplexing (OFDM) symbol index, using the position of the pilot subcarrier and the seed value, wherein the pilot sequences are inserted into a determined subcarrier position of the frame according to a pilot pattern, and wherein the pilot sequence is generated by applying a Zadoff-Chu sequence to each of a plurality of seed values including the seed value. - View Dependent Claims (7, 8, 9, 10)
