[File Format] ADSL_based_high-speedcabletelemetry

Description: 电缆遥测传输是测井系统传输数据的主要方式。针对测井电缆传输速率低、带宽窄等瓶颈问题 ,提出应用 ADSL 宽带网络接入的离散多音频调制(DMT)技术进行电缆传输的调制和解调 ,从理论上对此技术进行了详细分析 ,并通过计算机仿真试验 ,证明该方法对于提高电缆的频带利用率是可行的。-Cable telemetry transmit is a main way of data transmission in well logging systems. In this paper , due to a variety of shortcoming of logging cable , such as low transmit speed and narrow bandwidth , a DMT technology with the application of ADS L wide band is presented. This technology is analyzed theoretically in detail , and it has been proved that this method is feasible in increasing the bandwidth using efficiency of the cable by compute emulation.

[3G develop] OFDM

Description: 基于自适应压扩法降低OFDM系统的峰均比。正交频分复用（OFDM，Orthogonal Frequency Division Multiplexing）技术可以出色的对抗抗多径衰落、消除码间干扰且具有极高的频谱利用率。此外它还采用了快速傅立叶变换，大大降低了收发机的实现复杂度，因此被广泛地应用于HDSL、ADSL、DAB、HDTV、WLAN等领域中。但是，目前OFDM技术还有很多关键问题没有得到有效解决，如对频偏敏感、高峰均功率比问题等，这些都限制了OFDM技术的近一步广泛应用。本论文主要围绕自适应压扩法降低峰均功率比问题展开论述，并利用matlab软件完成了仿真。主要做了以下工作：论文首先回顾OFDM发展历程，说明了该技术的优缺点，讲解了OFDM技术原理，介绍了OFDM信号的产生过程，并对OFDM信号的收发机制进行了仿真。接着，给出峰均功率比的定义和分布，分析了产生高峰均值的原因，简要地介绍了其它预畸变方法，如限幅法，峰值加窗，传统的压扩技术。最后，分析自适应压扩法降低PAPR的性能，并用matlab完成相关仿真。 -OFDM,Orthogonal Frequency Division Multiplexing
