Space-time coding with maximum diversity gains over frequency-selective fading channels

In this letter, we study space-time (ST) block coding for single carrier ze ro-padded (ZP) block transmissions through finite impulse response (FER) mu ltipath fading channels of order L. We prove that maximum diversity of orde r 2 (L + 1) is achieved with two transmit and one receive antennae. Simulat ions demonstrate that joint exploitation of multi-antenna diversity and mul tipath diversity leads to significantly enhanced performance.
