Kami menganggap modulasi fasa berterusan berkod blok masa ruang (STBC-CPM), yang mempunyai kelebihan kedua-dua STBC dan CPM pada masa yang sama. Titik lemah STBC-CPM ialah kecekapan spektrum ternormal (NSE) dihadkan oleh keortogonan parameter STBC dan CPM. Tujuan kajian ini adalah untuk menambah baik NSE daripada STBC-CPM. The NSE bergantung kepada kadar penghantaran (TR), kadar ralat bit (BER) dan lebar jalur yang diduduki (OBW). Pertama, untuk menambah baik TR, kami menyesuaikan kuasi ortogonal-STBC (QO-STBC) untuk empat antena pemancar dan kod Toeplitz ortogonal kuasi kumpulan (Q-GOTC) untuk lapan antena pemancar, dengan mengorbankan ortogonal. Kedua, untuk menilai BER, kita terbitkan a BER anggaran STBC-CPM dengan STBC bukan ortogonal (NO-STBC). Hasil analisis teori dan simulasi menunjukkan bahawa NSE boleh diperbaiki dengan menggunakan QO-STBC dan Q-GOTC. Ketiga, yang OBW bergantung pada parameter CPM, oleh itu, pertukaran antara NSE dan parameter CPM dipertimbangkan. Simulasi komputer menyediakan set calon parameter CPM yang mempunyai lebih baik NSE. Akhirnya, penyesuaian STBC bukan ortogon kepada STBC-CPM boleh dilihat sebagai generalisasi kajian oleh Silvester et al., kerana STBC ortogonal boleh dianggap sebagai kes khas STBC bukan ortogon. Juga, penyesuaian Q-GOTC kepada CPM boleh dilihat sebagai generalisasi surat kami sebelumnya, kerana skema modulasi linear boleh dianggap sebagai kes khas modulasi bukan linear.

Abstract: We consider space time block coded-continuous phase modulation (STBC-CPM), which has the advantages of both STBC and CPM at the same time. A weak point of STBC-CPM is that the normalized spectral efficiency (NSE) is limited by the orthogonality of the STBC and CPM parameters. The purpose of this study is to improve the NSE of STBC-CPM. The NSE depends on the transmission rate (TR), the bit error rate (BER) and the occupied bandwidth (OBW). First, to improve the TR, we adapt quasi orthogonal-STBC (QO-STBC) for four transmit antennas and quasi-group orthogonal Toeplitz code (Q-GOTC) for eight transmit antennas, at the expense of the orthogonality. Second, to evaluate the BER, we derive a BER approximation of STBC-CPM with non-orthogonal STBC (NO-STBC). The theoretical analysis and simulation results show that the NSE can be improved by using QO-STBC and Q-GOTC. Third, the OBW depends on CPM parameters, therefore, the tradeoff between the NSE and the CPM parameters is considered. A computer simulation provides a candidate set of CPM parameters which have better NSE. Finally, the adaptation of non-orthogonal STBC to STBC-CPM can be viewed as a generalization of the study by Silvester et al., because orthogonal STBC can be thought of as a special case of non-orthogonal STBC. Also, the adaptation of Q-GOTC to CPM can be viewed as a generalization of our previous letter, because linear modulation scheme can be thought of as a special case of non-linear modulation.
