Extended balanced space-time block coding (EBSTBC) is able to achieve large coding gain and guarantee full diversity for any number of transmit antennas. However, the calculation of feedback information at the receiver employs exhaustive searching scheme which is at a high complexity. In this work, a low-complexity calculating scheme of feedback information is proposed for the receiver in EBSTBC systems. The scheme firstly choose the coding matrix according to the channel state information (CSI), and the value of extension parameters for achieving maximum coding gain are decided, then the two parts of the information are sent to the transmitter as the feedback information. Theoretical analysis and simulation results show that the calculating complexity of feedback information is greatly decreased, and almost the same reliability performance is achieved as the former scheme.

“…For that reason, the fusion center needs n+d feedback bits (n≥3) to select any possible ECBSTBCs where Eksim & Celebi, 2009b;Eksim, 2010b). n-2 feedback bits are needed to achieve full diversity as in Cooperative Balanced Space-Time Block Codes (CBSTBC) (Eksim & Celebi, 2007).…”

The original proposal of the extended balanced space–time block coding (EBSTBC) and its special subsets like balanced space–time block coding utilize all available transmit antennas to guarantee full diversity and to maximize the coding gain when few bits of feedback from the destination to the source are available. Because of the construction technique of EBSTBC, an antenna out of N transmit antennas does not contribute coding gain. To prevent this, a novel EBSTBC design and transmit scheme is proposed. This scheme transmits only N − 1 antennas out of N antennas and an antenna that maximizes the received signal‐to‐noise ratio at the destination doubles its transmit power. The proposed scheme improves performance of the EBSTBC and its subsets and outperforms closed‐loop extended orthogonal space–time block codes, phase feedback based extended space–time block codes, partial phase combining and transmit antenna selection schemes. The difference in performance becomes more prevalent in the presence of feedback errors. The proposed technique can be applied for orthogonal space–time block codes and quasi‐orthogonal space–time block codes if the destination informs the source which antenna has the highest gain.
