This paper, starting from the relation which should be satisfied for establishing non-synchronious balance state and several approximate conditions. derives an equation which describes nonsynchronious balance state, From which the pull-in range of BPSK RML can be found out an explicit of acquisiton mechanism is given. The paper also analysis the influences of the uncompensated time delay on the average probability of bit error and the tracking phase varlance. The numerical solution, which can be found by using computer, shows that these influences can be ignored when τ/T_0<0.2.

The transmission performance of the one-dimensional discrete cosine transform (1D-DCT) source/channel coding using (7, 4) Hamming code is discussed. It is assumed that the probability density of DC coefficient in the 1D-DCT is Gaussian, while the probability density of AC coefficient is Laplacian. Under these conditions, theoretical and simulation results with different transmitted data rate and different Pe (probability of Bit Error) are presented. The theoretical results are more conformable...

The transmission performance of the one-dimensional discrete cosine transform (1D-DCT) source/channel coding using (7, 4) Hamming code is discussed. It is assumed that the probability density of DC coefficient in the 1D-DCT is Gaussian, while the probability density of AC coefficient is Laplacian. Under these conditions, theoretical and simulation results with different transmitted data rate and different Pe (probability of Bit Error) are presented. The theoretical results are more conformable to simulation than D. R. comstock & J. D. Gibson. The studies also show that under the same total transmitting data rate channel coding can improve the SNR of the reconstructed image when Pe is greater or equal to 10-3, In the contrary, when Pe is less than 10-4, Channel coding cann't improve the SNR of the reconstructed image but make SNR decrease.

本文讨论了(7,4)汉明码和其它几种纠错码用于1D—DCT信源编码的传输性能,并假设DCT的直流系数是高斯分布,交流系数是拉普拉斯分布。在上述条件下,对不同的平均比特率及不同的信道误码率进行了理论分析,并对“女孩”图象进行了计算机模拟,所得的理论结果和模拟结果比D.Comstock和J.D.Gibson的结果更为吻合。研究还表明:在传输码率相同的条件下,当P_c≥10_(-8)时,增加信道纠错编码对于恢复图象的质量(SNR)有一定改善;当P_c<10_(-4)时,增加信道纠错编码不能改善恢复图象的SNR。

Up to now, to the author's best knowledge, there docs not exist a simple and convenient way forcomputing probability of bit error in underwater digital communication. The aim of this paper is toprovide such a way.In sonar, it is usual to estimate probability of bit error with detection threshold and ReceiverOperating Characteristic (ROC) curves. But, this is troublesome. The author's way replaces thresholdand ROC curves with the concept of Signal-Noise-Ratio Excess (SNRE) which is related to SNR,and the author's analysis gives the relationship between SNR and detection index.Mathematicallyexpressed, they are eqs.(8-10). Thus, estimate of probability of bit error is simplified.The author also considers some factors that influence the estimate of bit error: fading channel,diversity reception and error correcting decoding, etc. The author gives eqs.(11-15) for accountingfor the influence of these factors.Finally a numerical example appears to show that the author,s way is indeed simple and convenient.
