Digital radio

Digital 2 way radio is the digital technology to design digital radio. Digital radio is to speech signal digital, with the digital code spread form, that is, radio frequency transmission all of the modulation are digital. Only directly uses the digital signal processor intercom is the real meaning of the Numbers on the intercom, and use digital control signal interphone (such as cluster system intercom) does not belong to the digital radio. Digital radio has many advantages, it is can better use of spectrum resources, and the cellular digital technology similar, digital radio can be a designated in the channel such as 25 KHZ carry more users, improve spectrum efficiency, this is a kind of solving frequency crowded solutions, has long-term significance.
Second is to improve the voice quality. As digital communication technology in the system function with error correction, and than analog interphone, can be in a range of signal environment more widely, achieve better speech audio quality, its reception to audio noise will be more less, the voice more clearly.
The last point is, increase and improve the voice and data integration, change control signal communication distance increases with the decrease of weakness, and similar integrated analog voice and data than system, digital radio can provide better data processing and interface function, so as to make more data applications can be integrated into the same two-way wireless communication station structure of voice and data services to integrated more perfect and more convenient.
