求翻译：第二我将谈谈最具挑战性的项目：它就是V.34 synchronize modem project的设计和开发。它是Canada航空局的一个导航通讯系统之一，要求performance相当高，并且需要重新design synchronize V.34 modem。是什么意思？

Secondly, I will talk about the most challenging project: it is a V.34 synchronize modem project design and development. It is the Canada Aviation Authority is one of a navigation and communication systems require high performance, and the need to re-design synchronize V.34 modem.

2 I will turn to the most challenging project V34synchronize modem: It is the design and development project. It is a navigational Canada Aviation Board of one communication system performance requirements, and need to re-design was quite high, synchronize V34 modem.

Second I will chat the most challenging project: It is the V.34 synchronize modem project design and the development.It is Canada air bureau's one of navigation communication systems, requests performance to be quite high, and needs again design synchronize V.34 modem.

Next I will talk about the most challenging of projects: it is V.34 synchronize modem design and development of the project. It is one of the Canada Aviation Authority navigational communications systems requiring high performance, and design synchronize V.34 modem again.

Second I will talk about the most challenging project: It is design and development of V.34 synchronize modem project. It whether Canada aviation one of office navigate communication system one of, require performance to be quite high, and need design synchronize V.34 modem again.
