- In addition , this paper discusses the application of the parameter - induced stochastic resonance in the m - ary pam signal transmission , and explains the mechanism to stochastic resonance in a new view . we found that the single well is able to distinguish different signal levels , based on which the theory for m - ary pam signal transmission via parameter - induced stochastic resonance was briefly developed . the error code rate of m - ary pam signal was obtained
此外，本文还初步探讨了参数诱导的随机共振在多进制数字调制信号传输中的应用，从不同的观点解释随机共振形成的机理，充分认识到非线性系统单势井的信号处理能力，并给出多进制信号误码率的理论公式，仿真实验表明这个研究方向具有很好的研究前景。 - Subsequently , taking into consideration the characteristics of audio data over internet including delay , jitter , packet loss and etc . , we propose a series of methods for solving this above problems , such as pre - storage technology , buffer technology , dynamic adjustment of the voice - coding rate to the state of network and integrated media synchronization playing mechanism , and etc . in the end , simulation on 10 / 100m lan is made using the above methods , and the result of the experiment demonstrates the method has good performance and can improve the quality of the audio data transmission
其次本文还深入研究了语音数据在非实时的internet数据网上的传输特性，这些特性包括延时、延时抖动、数据包丢失等。在本文的设计方案中提出了针对这些问题的解决方法，包括预取机制、设置缓冲区技术、动态速率调节技术以及媒体综合同步播放机制等。最后采用这些方法在10 100m局域网上做了仿真实验，实验结果表明本文提出的方法是有效的，在网络状况恶劣的情况下能够改善语音播放质量。 - The mpeg2 is divided into the portrait quantity for high code rate of a few and different compression method , i good , but the space and mjpeg is basic same alike ; ibp the code rate is small , and the space request small , but the portrait quantity is badly , and in all likelihood synthesize the empress portrait the painting to speak for itself . therefore the one mpeg2 can t satisfy to unify the request of the format . explain : ocean company will plait of many formats of new product support that release , can support the dv25 , dv50 , mpeg2 i , mpeg2 ibp . etc .
8mpeg2分为几种不同的压缩方式， i帧高码率的图象质量好，但是存储空间与mjpeg基本相同ibp帧码率小，空间要求小，但是图象质量很差，多半合成后图象劣画很明显。所以单一mpeg2不能满足统一格式的要求。解释：大洋公司将推出的新产品支持多格式混编，可以支持dv25 dv50 mpeg2 i mpeg2 ibp等。 - 7 , i mpeg2 adoption the inside compress the calculate way , fundamental similar to mjpeg . the mpeg2 differentiation i contain code rate upper limit , because of but always have the portrait to hurt of , but the mjpeg has no a code rate upper limit , can cope with to the circumstance that the portrait quantity request very the engrave
7 i帧的mpeg2只采用帧内压缩算法，基本和mjpeg相同。区别是i帧的mpeg2有码率上限，因而总是有图象损伤的，而mjpeg没有码率上限，可以应付对图象质量要求很苛刻的情况。 - This paper discusses the results in ricean channel in addition . the analysis of rayleigh and ricean channel are based on two cases , state information ( si ) , and no state information ( nsi ) . while the code rate approaching to zero , the shannon limit of bsc channel model is 0 . 37db , the result of awgn ’ s is - 1 . 59db , of rayleigh si is - 2 . 31db , of rayleigh nsi is - 1 . 45db , of riceansi is - 2 . 31db , and of ricean nsi is - 1 . 44db
当码率趋近于0时bsc信道下的香农限为0 . 37db , awgn信道下的香农限为- 1 . 59db ,瑞利信道下信道增益已知时的香农限为- 2 . 31db 、信道未知时的香农限为- 1 . 45db ,莱斯信道下信道增益已知时的香农限为- 2 . 31db ,信道增益未知时香农限为- 1 . 44db 。
