In this paper, the performance of Complex orthogonal space-time block codes (COSTBCs) [1] [2] [3] with transmit antenna selection (TAS) with reduced feedback bit in a Rayleigh fading channel is analyzed. Out of the total of Lt transmit antennas, scheme-I, select best 8 transmit antenna, scheme-II, select best four group of each group consist of two transmit antenna, scheme-III, select best two transmit antenna and rest of the six antenna select randomly. Scheme-I gives best compare to Scheme-II, Scheme-III. But within this all schemes, Scheme-III requires less feedback bit compare to other schemes. All three Schemes of TAS have been presented in the article.

Abstract


In this paper, the performance of Complex orthogonal space-time block codes (COSTBCs) [1] [2] [3] with transmit antenna selection (TAS) with reduced feedback bit in a Rayleigh fading channel is analyzed. Out of the total of Lt transmit antennas, scheme-I, select best 8 transmit antenna, scheme-II, select best four group of each group consist of two transmit antenna, scheme-III, select best two transmit antenna and rest of the six antenna select randomly. Scheme-I gives best compare to Scheme-II, Scheme-III. But within this all schemes, Scheme-III requires less feedback bit compare to other schemes. All three Schemes of TAS have been presented in the article.
