Güçlüoğlu, TansalPanayırcı, Erdal2019-06-282019-06-28200812219-54912219-5491https://hdl.handle.net/20.500.12469/1612This paper presents a performance analysis of space-time coded systems with transmit antenna selection over frequency selective fading channels when the erroneously estimated fading coefficients are available only at the receiver. An upper bound on the pairwise error probability is derived and numerical examples are presented. The analysis does not assume any specific coding or channel estimation algorithm. With imperfect channel state information (CSI) used both at the antenna selection and the space-time decoding processes the achievable diversity order does not decrease compared to perfect CSI scenario. copyright by EURASIP.eninfo:eu-repo/semantics/openAccessConference Object2-s2.0-84863759363
