Abstract

Spectrum resources are very valuable. This paper presents a pilot design for full frequency reuse system in the vertical Bell Labs layered space-time with distributed transmit antennas. In this system, the transmit antennas are placed distributed and the pilot symbols of adjacent 9 antennas are placed at different times or on different subcarriers. A simulation is carried out under the condition of three transmit and three received antennas, multipath Rayleigh fading channel, and antenna spacing of 500 meters. The simulation results show that, at the area averaged mean square error of 5×10, the propose method is superior by about 2dB to the traditional method in bit signal-to-noise ratio.
