Query: Unified Analysis of Transmit Antenna Selection/Space-Time Block Coding
  with Receive Selection and Combining over Nakagami-m Fading Channels in the
  Presence of Feedback Errors   Examining the effect of imperfect transmit antenna selection (TAS) caused by
the feedback link errors on the performance of hybrid TAS/space-time block
coding (STBC) with selection combining (SC) (i.e., joint transmit and receive
antenna selection (TRAS)/STBC) and TAS/STBC (with receive maximal-ratio
combining (MRC)-like combining structure) over Nakagami-m fading channels is
the main objective of this paper. Under ideal channel estimation and delay-free
feedback assumptions, statistical expressions and several performance metrics
related to the post-processing signal-to-noise ratio (SNR) are derived for a
unified system model concerning both joint TRAS/STBC and TAS/STBC schemes.
Exact analytical expressions for outage probability and bit/symbol error rates
(BER/SER) of binary and M-ary modulations are presented in order to provide an
extensive examination on the capacity and error performance of the unified
system that experiences feedback errors. Also, the asymptotic diversity order
analysis, which shows that the diversity order of the investigated schemes is
lower bounded by the diversity order provided by STBC transmission itself, is
included in the paper. Moreover, all theoretical results are validated by
performing Monte Carlo simulations.
