随着新技术的不断发展,数字期间有了越来越广泛的应用。在扩频系统中,已经开始研制数字相关解调器,从理论上讲,数字相关解调器必须有一个量化环节,因此,与模拟器件相关解调器相比,系统的信噪比会有所降低。但数字相关器件与模拟相关器件相比有更多的有点,模拟器件不容易做的大的时间带宽积,器件的性能对温度变化较敏感,而且编程困难,所以,数字相关解调的方案有独特的吸引力。-With the continuous development of new technology, digital has become increasingly widely used during the period. In spread spectrum systems, has started to develop digital correlation demodulator, in theory, digital correlation demodulator must have a quantitative aspect, therefore, associated with the analog device demodulator, system signal to noise ratio will be decreased. However, figures related to the relevant devices and analog devices with more than a little bit, analog devices is not easy to do big time bandwidth product, device performance is sensitive to temperature change, and programming have, therefore, the number of programs associated with demodulation unique appeal.
