Keeping in tune the global developments we are creating an institutional repository using DSpace Software (Digital Library Software). We are archiving institutional knowledge like, faculty papers, theses, and dissertations in PDF format at DSpace. Students can access this digital information anywhere in the campus.

| Abstract: | We analyze a sub-optimum transmit antenna selection (TAS) scheme in multiple input single output (MISO) systems equipped with N transmit antennas. We keep one antenna fixed and select the best among the remaining N −1 antennas. We assume spatially independent flat fading channel with perfect channel state information (CSI) at receiver and an ideal feedback link. We use Alamouti transmit diversity and derive the closed-form expressions of bit error rate (BER) and outage probability for BPSK constellation. We also compare performance of the sub-optimum scheme with performance of the optimum scheme using BER, outage probability expressions and number of feedback bits. |
