Abstract
In this paper, we review and analyze the space-time trellis codes with and without ideal beamforming. Space-time trellis code with ideal beamforming at transmitter termed as weighted space. Smart antenna technology provides a wide variety of options, ranging from single-input multiple-output architectures that collect more energy to improve the signal-to-noise ratio at the receiver, to multiple-input multiple-output (MIMO) architectures that open up multiple data pipes over a link. Atmospheric turbulence can cause significant performance degradation in free-space optical (FSO) communication systems. An efficient solution could be to exploit the temporal diversity to improve the performance of the FSO link.
