Design & Research Of The Cdma2000 1x Reverse Link

Nowadays the discussion about 3G Digital Cellular Mobile Communication Technologies is very hot. It is in sight that the execution of 3G. Which system we should adopt in our state has been very clear. cdma2000 Digital Cellular Mobile Communication Technology has become the first selection of China Unicom as the 3G standard. In this background, we lucubrate the cdma2000 lx system.The physical layer standard for cdma2000 lx reverse link systems is introduced in this paper. Based on the acquaintance, the design and implementation of a simulation model for the cdma2000 lx reverse link is presented with the communications system simulation of the software Matlab. There are transmitterand receiver in the simulation system of reverse link. Further more, we analyze the performance of this system. According to the experimental result, we believe that the simulation system almost reach to the object as it is required in the practical system, for example, BER. Therefore, the both system are quite approximate.We design a MONTE CARLO dynamic system simulation with the modularization conception. In this system, we encapsulate the same type data, so the engineers and researchers can simulate a lot of communication channels of the different Radio Configuration by only changing the parameters setting. The consequences of the simulation system demonstrate that the system is not only efficient but also convenient to the practice of the engineering and research. This system's communication channel include reverse Fundamental Channel Supplementary Channel 1 and 2 Dedicated Control Channel Common Control Channel Pilot Channel and Enhanced Access Channel. In this paper, we analyze the performance of this system in the different communication environment.Finally, we research the reverse link budget of cdma2000 lx based on the corresponding system simulation, and analyze whichmodels link budget we could adopt in 3G communication, and calculated the ullage of the utmost path and the largest bestrow range under different environment of the reverse link of cdma2000 lx.
