Özet
In this paper, we study and compare performance of joint transmit/receive antenna selection in MIMO-OFDM WLANs using dual polarized stacked circular microstrip antennas (SMP-SCP-ULA).At receiver side we use a flexible two-step selection algorithm (TSSA) and variable per-tone selection algorithm at transmitter side. The support of high data-rate MIMO spatial multiplexing communication in OFDM WLAN systems conforming to IEEE802.11n standard requires the use of compact antennas. Using antenna selection in conjunction with higher order modal SMP-SCP-ULA provides an additional performance improvement in terms of modal correlation and ergodic spectral efficiency.
