Error probability analysis of TAS/MRC-based scheme for wireless networks Conference Paper

abstract

• We develop the framework to analyze the symbol-error probability (SEP) for the scheme integrating transmit antenna selection (TAS) with maximal-ratio combining (MRC) used in wireless networks. Applying this scheme, the transmitter always selects an optimal antenna out of all possible antennas based on channel state information (CSI) feedbacks. Over flat-fading Rayleigh channel, we develop the closed-form SEP expressions for a set of commonly used constellations when assuming the perfect and delayed CSI feedbacks, respectively. We also derive the Chernoff-bounds of the SEP's for both perfect and delayed feedbacks. Our analyses show that while the antenna diversity improves the system performance, the feedback delay can significantly impact the SEP of TAS/MRC schemes. 2005 IEEE.
