A clock synchronization method used in ADSL systems based on Discrete Multitone(DMT) is presented.

文章提出了一种ADSL系统中基于离散多音调制解调结构的时钟同步方法。

The error correcting and decoding, interleave and and DMT modulation and demodulation are analyzed in detail.

分析了信道编译码方法、 交织与解交织及DMT调制与解调等关键技术。

The main works in the paper could be described as follow: Study the theory of ADSL and DMT, design and debug the high density 32 line ADSL board for co.

论文的主要工作：深入研究ADSL理论及其离散多音调制。设计、并实际开发了高集成度32路ADSL局端业务板。

The technology that using DMT, EG and PEG as material, using sodium benzene sulfonate as auxiliary antistatic agent to prepare the antistatic mother substance was studied.

研究了以DMT, EG, PEG为原料，苯磺酸钠等为辅助抗静电剂制备抗静电母粒的工艺。

The effects of concentration of N-VP and light sensitive agent DMT in the grafting solutions and irradiation time on the grafting yield in acid and basic mediums were investigated.

测定了接枝率与接枝液中N-VP单体浓度、光照时间、催化剂浓度等条件的关系。

From the comparison of the flat dilatometer test (DMT) and several other in-situ tests, a conclusion can be drawn that the DMT is very suitable for test parameter measurement of seaside silt.
