Dalam kertas ini, kod blok ruang-masa kadar penuh (STBC) baharu yang mempunyai sifat kuasi-ortogonal (QO) dicadangkan untuk QAM dan 8 antena pemancar. Kod ini direka bentuk dengan menggabungkan secara bersiri prapengoder berputar buruj sebenar dengan skema Alamouti. Sifat QO membolehkan penyahkodan ML dilakukan dengan pengesanan bersama hanya empat simbol sebenar seperti kerumitan penyahkodan minimum konvensional QO-STBC (MDC-QO-STBC). Walau bagaimanapun, kod yang dicadangkan dijamin untuk mencapai kepelbagaian spatial penuh untuk QAM am tidak seperti MDC-QO-STBC yang dibentangkan khusus untuk 4-QAM sahaja. Dengan keputusan simulasi komputer, kami menunjukkan bahawa kod yang dicadangkan mempamerkan prestasi ralat yang sama dan sedikit terdegradasi dengan MDC-QO-STBC untuk 4-QAM dan QO-STBC Sharma untuk 4 dan 16-QAM, masing-masing. Akhir sekali, kami membentangkan skema baharu yang diubah suai bagi kod asal supaya tiada sebarang ketakselanjaran penghantaran pada setiap antena pemancar, tanpa kehilangan prestasi ralat.

Abstract: In this paper, a new full-rate space-time block code (STBC) possessing a quasi-orthogonal (QO) property is proposed for QAM and 8 transmit antennas. This code is designed by serially concatenating a real constellation-rotating precoder with the Alamouti scheme. The QO property enables ML decoding to be done with joint detection of only four real symbols like the conventional minimum decoding complexity QO-STBC (MDC-QO-STBC). However, the proposed code is guaranteed to achieve full spatial diversity for general QAM unlike the MDC-QO-STBC which is specifically presented for only 4-QAM. By computer simulation results, we show that the proposed code exhibits the identical and slightly degraded error performance with the MDC-QO-STBC for 4-QAM and the Sharma's QO-STBC for 4 and 16-QAM, respectively. Finally, we present a new modified scheme of the original code so that there is no any discontinuity of transmission at each transmit antenna, without any loss of error performance.
