Kertas ini mencadangkan kaedah kawalan gelung luar bagi kawalan kuasa penghantaran cepat (TPC) untuk penghantaran data berkualiti tinggi seperti itu dengan purata kadar ralat bit (BER) sebanyak 10-6 dalam pengekodan saluran bersiri yang menggabungkan pengekodan konvolusi (dalam) dan Reed-Solomon (luar) untuk radio mudah alih DS-CDMA. Dalam kaedah yang dicadangkan, kawalan gelung luar dilakukan berdasarkan nilai kadar ralat blok perantaraan (BLER) yang diukur selepas penyahkodan saluran dalam. Oleh kerana bilangan ralat blok selepas penyahkodan saluran dalam jauh lebih besar daripada output akhir selepas penyahkodan saluran luar, prestasi pengesanan pantas perubahan mendadak dalam keadaan perambatan seperti bilangan multipaths dan frekuensi Doppler yang pudar, iaitu, bergerak. kelajuan stesen mudah alih, dicapai. Keputusan eksperimen menjelaskan bahawa BLER yang diukur selepas penyahkodan saluran luar dikawal dengan tepat kepada hampir nilai malar daripada frekuensi Doppler maksimum pudar rendah ke tinggi sehingga 480 Hz, dan BER yang diukur selepas penyahkodan saluran luar berada dalam julat satu. -tertib magnitud penerimaan kepelbagaian antena (sementara itu, nilai SIR sasaran selepas gabungan Rake berbeza dengan julat 2.5 dB).

Abstract: This paper proposes an outer loop control method of fast transmit power control (TPC) for high-quality data transmission such as that with the average bit error rate (BER) of 10-6 in serial concatenated channel coding combining convolutional (inner) and Reed-Solomon (outer) codings for DS-CDMA mobile radio. In the proposed method, the outer loop control is performed based on the measured intermediate block error rate (BLER) value after inner-channel decoding. Since the number of block errors after inner-channel decoding is much greater than that of the final output after outer channel decoding, fast tracking performance of the sudden changes in the propagation conditions such as the number of multipaths and fading Doppler frequency, i.e., moving speed of the mobile station, is achieved. The experimental results clarify that the measured BLER after outer channel decoding is accurately controlled to almost a constant value from the low to high fading maximum Doppler frequency of up to 480 Hz, and that the measured BER after outer channel decoding is within the range of one-order of magnitude of the antenna diversity reception (meanwhile, the target SIR value after Rake combining varied with the range of 2.5 dB).
