Then the influence of various parameters(numbers of antennas,average received SNR and selective-fading diversity) on ergodic capacity is analyzed.

Then the connection between selective-fading diversity and capacity is analyzed,which shows that the product of the time-selectivity order and the frequency-selectivity order is the key parameter for characterizing the outage probability and outage capacity.

Iterative interference cancellation based on decoding algorithm of space-time block coding in frequency-selective fading;

A blind adaptive decorrelating Rake receiver for CDMA communications over frequency-selective fading channels;

A data block transmission technology of Alamouti′s space-time block codes with two transmit antennas and one receive antenna in single-carrier system was proposed over frequency-selective fading channels.

The multipath propagation caused by it in the frequency is a generalized Rayleigh_distribution in mathematics, and the reason that causes frequency selective fading.

When transmitting signal at high bit rate, the Reentry Remote Sensing channel presented an obvious character of frequency selective fading and the two-path model could well model this channel.

To cope with frequency selective fading caused by intersymbol interference(ISI), a MIMO decision feedback equalizer (DFE) was used to change the channel into a freqency non-selective one, which was jointly optimized with a second order phase-locked loop(PLL) to compensate the carrier phase shift.
