A Genetic Particle Filtering Equalization in Frequency Selective Fading Channels;

The proposed method has a simple close-form solution,which avoids the process of iterative searching and has less computational complexity,and it is suitable for slow time-varying frequency selective fading channels.

A novel system based on cooperative distributed space-time block code and multi-carrier code division multiple access(DSTBC-MC-CDMA) is proposed which works well on multiple single-antenna users wireless networks in frequency selective fading channel.

This paper generalize diagonal algebraic space time block codes over flat fading channel to frequency selective fading channel and proposes a diagonal space frequency(DSF) block codes.

The transmission characteristic of frequency selective fading channel is summarized.

Because using OFDM, a frequency-selective fading channel can be transformed into multiple frequency-flat fading sub-channels, in the coding process, spatial diversity (due to multiple antennas) is integrated with frequency diversity (due to delay spread), therefore, the proposed code can provide higher diversity gain than space-time code alone.

Focusing on the problem that the bit error rate performance of the space-time block codes decreases in frequency-selective fading channels,a time-reversal coordinate interleaved orthogonal coding design(TR-CIOD) is proposed.
