In this paper,the measurement model of the OFDM modulator is developed to include the widely existed weak frequency selectivity(WFS) in the measurement system of the OFDM modulator.

Mechanism underlying the frequency selectivity of central auditory neurons: near-CF or off-CF?;

<Abstrcat>With respect to the Multiple-Input Multiple-Output (MIMO) architecture under the frequency-selective fading environment,this paper introduces the Direct-Sequence Spread-Spectrum (DSSS) operation into each transmit-antenna branch so as to make the frequency-selective fading channel vectorizable.

Frequency-selective frequency hopping(FH) cosite dinterference is a typical long impulse response interfe-rence.

Space-frequency block coding technique over frequency selective correlated channels;

The simulation of the rake reception under the frequency selective slow fading channels indicates that it is effective to counteract the multipath fading.

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.
