    Outage Probability of TAS/MRC Systems over Nakagami-m Fading Channels with Correlation

    By Rajkishur Mudoi, Rupaban Subadar

    Abstract: This paper analyzes the outage probability of a multiple-input multiple-output (MIMO) transmit antenna selection with a maximal ratio combining (TAS/MRC) system considering equal and exponential correlation among the input branches of MRC receiver. In TAS/MRC system the transmitter selects the best antenna out of the total transmit antennas based on the channel state information (CSI) of each user. A closed form expression has been derived for outage probability considering Nakagami-m …

    ABER of Transmit Antenna Selection with Maximal Ratio Combinining-MIMO System over Nakagami-m Fading Channels

    By Rajkishur Mudoi, Hubha Saikia, Rupaban Subadar

    Abstract: AbstractThis paper presents the average bit error rate (ABER) of a multiuser, multiple input and multiple output (MIMO) wireless system. Transmit antenna selection at the base station and maximal ratio combining at the receiver is considered for downlink transmission. For coherent and noncoherent modulation schemes, ABER performance of the system is analyzed. The closed form expressions have been derived for ABER considering Nakagami-m fading channels. The effects of fading parameter …

    Effect of Outdated CSI in a Multiuser TAS/MRC System over Correlated Nakagami-m fading

    By Rajkishur Mudoi

    Abstract: The TAS/MRC system is a widely accepted technique to reduce the complexity level of a multiuser MIMO system with little reduction in the performance. This increases the practical applicability of TAS/MRC system. In TAS/MRC algorithm the channel state information (CSI) is provided to the transmitter for selection of best transmitting antenna for better system performance. However, two important factors may reduce the performance of the TAS/MRC system considerably, out dated …
