tgrr yggg ggg yttt Space time block coding (STBC) and beamforming techniques are two emerging technologies that can be employed at base station with multiple antenna to provide transmit diversity and beamforming gain to increase signal-to- noise ratio (SNR) of the downlink. STBC utilizes a diversity antenna system where the antenna spacing is usually required to be large enough, say 10 times wavelength of the carrier for a uniform linear array (ULA) in small angular spread environments, to obtain low-correlation/independent fading channels. While the beamforming antenna needs to achieve spatial directivity and the signals received at and/or transmitted from all antennas must be correlated or coherent. So the antenna spacing should usually be very small, e.g. half wavelength for ULA.
