Method for eliminating reception interference signal of space-time block coded orthogonal frequency division-multiplexing system in high-speed mobile channel

A method for eliminating a reception interference signal of an STBC-OFDM system in a high-speed mobile channel, comprising:

• a first step of assigning orthogonal code to a sub-carrier axis and estimating a difference between frequency responses of adjacent sub-carriers;
• a second step of obtaining first temporary decision symbols by performing comparison on the estimated difference;
• a third step of obtaining second temporary decision symbols using the first temporary decision symbols;
• a fourth step of eliminating the SCI term using the second temporary decision symbols and obtaining third temporary decision symbols;
• and
• a fifth step of obtaining final data symbols using the third temporary decision symbols.

A method for eliminating a reception interference signal of an STBC-OFDM system in a high-speed mobile channel, comprising:

• a first step of applying an encoding rule that can be applied to the STBC-OFDM system to prevent generation of channel interference;
• a second step of eliminating interference between antennas and achieving maximum ratio combination by transmitting a signal in a symbol period using the antennas;
• and
• a third step of employing a comb type coding method to reduce a PAR.
