随着社会的进步和技术的发展,人们对通信手段的消费水平和需求日益提高。传统的电话方式已逐渐无法满足这个分秒必争的社会形态,所以如何使电话具有可移动性,特别是大范围的可移动性(漫游性)具有非常重要的意义。分集技术是指通过查找和利用自然界无线传播环境中独立的(至少是高度不相关的)多径信号来实现,简单的说,如果一条无线传播路径中经历了深度衰落,而另一条相对独立的路径中可能仍包含着较强的信号,因此可以在多个信号中选择两个或更多的信号进行合并,这样可以同时提高接收端的瞬时信噪比和平均信噪比。分集技术是移动通信的一种抗衰落技术,是一种用相对较低廉的投资就可以大幅度的改进无线链路性能的强有力的接收技术。利用MATLAB对频率分集技术在移动通信中应用的仿真,可以验证频率分集技术在移动通信中的应用为补偿衰落信道损耗所起的功用。

Along with social advance with technical development, people to consumption level that correspondence means with require with to increases increasingly.The traditional telephone method can't satisfy a social appearance for seizing every minute and second already and gradually, so how to make telephone had to can move the sex, the especially big scope can move the sex( travel extensively the sex) has the count for much meaning.The cent gathers the technique is to points to pass to check to seek with make use of the nature lead-in spreads independent many paths signal in inside in environment to realize, say in brief, if a lead-in spreads to experience in the path the depth decline, but another an opposite and independent path inside may still include the stronger signal, therefore can win election to choose two moment for or more signals proceeding merging, like this can at the same time increasing receiving carryings letter noise ratio peace in several signals all letter roise ratio.The cent gathers the technique is a kind of anti- to move the correspondence to decline the technique, is a kind of using the opposite cheap investment can the then significant improvement lead-in network function receive the technique powerfully.Make use of the MATLAB to gather the technique to the cent of frequency to imitate appliedly in move correspondence true, can verify the frequency the cent gather the technique at move application in the correspondence as to compensate to decline the letter the effect that way rises when exhausting.

Raise increasingly along with the progress and technical developments, the people's consumption level to the correspondence means and needs of the society.The traditional telephone method has already can'ted satisfy this social appearance that seize every minute and second gradually, so how make telephone have can move sex, the especially big scope can move sex( travel extensively sex) to have the count for much meaning.The cent gather the technique to mean to pass to check to seek and make use of the nature lead-in dissemination environment to carry out in many independent path signals, say in brief, if experienced the depth to decline in a lead-in dissemination path, but another an opposite and independent path in the possibility still includes the stronger signal, so can win election to choose two or more signalses to carry on the merger in several signals, thus can the moment that raise to receive to carry believe the 噪 to compare the peace to all believe the 噪 to compare at the same time.The cent gathers the technique is a kind of anti- that moves the correspondence to decline the technique, is a kind of to use the opposite cheaper investment and can receive the technique powerfully with the significant improvement lead-in network function.Make use of the MATLAB to gather the technique to the frequency separately to really imitate appliedly in move correspond by letter, can verify the frequency to gather the application that the technique is in move correspond by letter for cent for the repair declines to believe the way to exhaust rise of effect.

Along with society's progress and technical development, the people enhance day by day to the means of communication consumption level and the demand. The traditional telephone way has been unable gradually the form of society which satisfies this to seize every second and minute, therefore how enable the telephone to have the removability, specially the wide range removability (roaming nature) has the extremely vital significance. The diversity technology is refers through the search and in the use nature wireless dissemination environment independent (is at least highly non-correlated) the multi-diameter signal realizes, simple saying, if in a wireless path of propagation has experienced the depth decline, but in another relatively independent way still was possibly containing the strong signal, therefore might choose two or more signals in many signals carries on the merge, like this might simultaneously enhance receiving end the instantaneous signal-to-noise ratio and the average signal-to-noise ratio. The diversity technology is the mobile communication one kind of anti-fading technology, is one kind uses the relative inexpensive investment to be possible the large scale improvement wireless link performance powerful receive technology. Using MATLAB to the frequency diversity technology in the mobile communication the application simulation, may confirm the frequency diversity technology in the mobile communication application the function which loses for the compensation fading channel gets up
