| 英文摘要 | a novel ameliorated phase generated carrier (pgc) demodulation algorithm based on arctangent function and differential-self-multiplying (dsm) is proposed in this paper. the harmonic distortion due to nonlinearity and the stability with light intensity disturbance (lid) are investigated both theoretically and experimentally. the nonlinearity of the pgc demodulation algorithm has been analyzed and an analytical expression of the total-harmonic-distortion (thd) has been derived. experimental results have confirmed the low harmonic distortion of the ameliorated pgc algorithm as expected by the theoretical analysis. compared with the traditional pgc-arctan and pgc-dcm algorithm, the ameliorated pgc algorithm has a much lower thd as well as a better signal-to-noise-and-distortion (sinad). a thd of below 0.1% and a sinad of 60 db have been achieved with pgc modulation depth (value) ranges from 1.5 to 3.5 rad. the stability performance with lid has also been studied. the ameliorated pgc algorithm has a much higher stability than the pgc-dcm algorithm. it can keep stable operations with lid depth as large as 26.5 db and lid frequency as high as 1 khz. the system employing the ameliorated pgc demodulation algorithm has a minimum detectable phase shift of 5 mu rad/root hz @ 1 khz, a large dynamic range of 120 db @ 100 hz, and a high linearity of better than 99.99%.; A novel ameliorated phase generated carrier (PGC) demodulation algorithm based on arctangent function and differential-self-multiplying (DSM) is proposed in this paper. The harmonic distortion due to nonlinearity and the stability with light intensity disturbance (LID) are investigated both theoretically and experimentally. The nonlinearity of the PGC demodulation algorithm has been analyzed and an analytical expression of the total-harmonic-distortion (THD) has been derived. Experimental results have confirmed the low harmonic distortion of the ameliorated PGC algorithm as expected by the theoretical analysis. Compared with the traditional PGC-arctan and PGC-DCM algorithm, the ameliorated PGC algorithm has a much lower THD as well as a better signal-to-noise-and-distortion (SINAD). A THD of below 0.1% and a SINAD of 60 dB have been achieved with PGC modulation depth (value) ranges from 1.5 to 3.5 rad. The stability performance with LID has also been studied. The ameliorated PGC algorithm has a much higher stability than the PGC-DCM algorithm. It can keep stable operations with LID depth as large as 26.5 dB and LID frequency as high as 1 kHz. The system employing the ameliorated PGC demodulation algorithm has a minimum detectable phase shift of 5 mu rad/root Hz @ 1 kHz, a large dynamic range of 120 dB @ 100 Hz, and a high linearity of better than 99.99%.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-12-12t07:57:53z no. of bitstreams: 1 an ameliorated phase generated carrier demodulation algorithm with low harmonic distortion and high stability.pdf: 821169 bytes, checksum: 57be41354bc3ad441f018418669403e9 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-12-12t08:06:57z (gmt) no. of bitstreams: 1 an ameliorated phase generated carrier demodulation algorithm with low harmonic distortion and high stability.pdf: 821169 bytes, checksum: 57be41354bc3ad441f018418669403e9 (md5); made available in dspace on 2010-12-12t08:06:57z (gmt). no. of bitstreams: 1 an ameliorated phase generated carrier demodulation algorithm with low harmonic distortion and high stability.pdf: 821169 bytes, checksum: 57be41354bc3ad441f018418669403e9 (md5) previous issue date: 2010; manuscript received july 05, 2010; revised august 29, 2010; accepted september 20, 2010. date of publication october 07, 2010; date of current version november 12, 2010. this work was supported by national science foundation of china under grant 61077059 and grant 41074128, in part by the national high technology research and development program of china (863 program) under grant 2009aa11z212, and in part by the knowledge innovation program of chinese academy of sciences under grant iscas2008t05.; 其它 |
