A Quadrature Coded OFDM for Reducing Effects of Frequency Offset in Wireless Transmission System |
|
| Authors: | TONG Xue-jian JI Hong YUE Guang-xin |
| Abstract: | A new quadrature coded OFDM system is proposed. The transmitted data symbols are grouped in such format that the in phase side and the quadrature side of the symbols are arranged in opposite order. By analysis and simulation, the performance of the new system can be improved greatly, as well as the harmful influences on the system owing to frequency offset can be reduced effectively, which can combat the disadvantages of OFDM system. |
| Keywords: | orthogonal frequency division multiplexing( OFDM ) frequency offset interchannel interference( ICI ) equal gain combination( EGC ) |
