“…Several approaches have been suggested in the literature to solve this problem, including the transmission of the short training sequence [ 29 , 30 ] or the use of precoders [ 31 33 ]. However these semiblind techniques cannot be employed in a noncooperative scenario since they need to modify the transmitter, which has been implemented utilizing the adaptive pilot assisted channel estimation scheme (APACE) proposed by [ 18 ] and by some modification at the precoder and decoder in the proposed scheme, based on which the analysis has been shown in [ 34 ] for the STBC with code rate up to 1. Despite the literature available universally, none of the algorithms is able to estimate the channel matrix for general STBCs without modification of the pilot training symbols and precoding.…”

“…It is really cheering that wireless systems have been made use of abundantly throughout the length and breadth of the cosmos to cater to the everrocking needs of the inquisitive human being and the sophisticated machines to exchange communications in between them, regardless of the places in which they are situated [1,2]. Wireless systems generally are home to a transmitter, a radio channel and a receiver and are characterized by the number of their inputs and outputs [3,4].…”

“…Among the parameters to adapt at the transmitter, the work has been confined to find the optimal algorithm associated with the possible maximal constellation size. To be able to select the optimal algorithm under certain channel conditions, we need to know accurately beforehand the spectral efficiency of the algorithms at different signal to noise ratio (SNR) which has been shown in [10]. Although several theoretical upper bounds [11] of the spectral efficiency have been suggested, e.g.…”
