摘要
在第三代通信系统中,无线网络全部采用了数字化传输,从而对以往的模拟传输提出了根本性的变革。WCDMA是全球三大主流标准之一,其调制解调也与 GSM有本质上的不同。本文重点论述了该系统中所采用的调制解调的原理及方法,]简述了Maxim2450调制解调的应用。
The digital signal processing and transmission have been used in the third generation wireless communication system, and it brings forward a new revolution. The WCDMA system is one of the three main criterions in the world, and it is essentially different from GSM in the modulate/demodulate area. This article explains the theory and method of modulator and demodulator. At the same time, it briefly introduces the application of IC Maxim2450.
