This paper proposes a directive antenna diversity reception scheme for an adaptive modulation/time division multiple access (TDMA)/time division duplex (TDD) system to achieve high quality, high bit rate and high spectral efficient data transmission in high mobility land mobile communication environments. In mobile stations, a directive antenna is applied to equivalently reduce the observed variation speed of the fading channel. At each branch, the offset frequency (f_ltoffgt) and f_ltoffgt-canceled fading variation are estimated to improve accuracy of the propagation path characteristics estimation even in high maximum Doppler frequency (f_d) environments. Computer simulation confirms that the proposed scheme can achieve successful variable rate transmission in fast fading environments.
