| Abstract: | Satellite navigation receivers are designed with regard to the fact that the levels of satellite signals reaching the earth's surface are weak and relatively unchanged.This paper firstly describes the concepts relating to the near-far problem and particularly analyzes the objective of near-far effect mitigation aimed at raising near-far ratio,then summarizes in depth the existing solutions and their relative merits,then further proposes a solution to near-far effect mitigation by employing adaptive anti-int... |
