Apparatus and method for transmitting and receiving a pilot signal in a communication system using a multi-carrier modulation scheme |
摘要 |
In an MCM communication system in which one frame includes at least one pilot symbol of a predetermined length and at least one data symbol of the predetermined length, to transmit the pilot symbol for time synchronization and frequency synchronization, a first pilot sequence of a length shorter than the predetermined length is generated, and a second pilot sequence of a length shorter than the predetermined length is generated. Here, the second pilot sequence is different from the first pilot sequence. The first and second pilot sequences are repeated a predetermined number of times. The pilot symbol is generated by combining the repeated first and second pilot sequences, and then transmitted.
