| Abstract: |
| Near-far effect is an important factor that affects the reception performanc
e in CDMA（Code Division Multiple Access） TT&C systems. The impact of near
-far effect on the reception performance in the multi-station TT&C system is a
nalyzed，and the necessity of power control is presented. Finally，a method and st
rategy of power control is given，which can be considered as a reference in mult
i-station CDMA TT&C system. |
