Performance of MISO Systems with Alamaouti Transmit Diversity and Antenna Selection in TDD and FDDof time division duplex (TDD) and frequency division duplex (FDD). We consider a MISO system equipped with 2. transmit antennas. In the total . pairs of antenna, there is a spatial correlation in each pair (two antennas) only. We assume quasi-static Rayleigh fading channels. We select one pair of an

Performance Comparison of Different Diversity and Combining Techniques Over Gamma–Gamma FSO Linknk performance degrades due to atmospheric turbulence. Like RF wireless communication link, the diversity and combining techniques were found effective in FSO link too. This paper compares BER performance of various diversity and combining techniques. We have simulated maximum ratio transmission (MR
