Effect signalc threshold.Sign () be sign function, represent when in bracket value as positive number when sign () take 1, when value is in bracket
Negative or sign () takes -1 when 0.f(Ri,psc(k)=P) be j-th neighbor pilot in i-th MR weighted value.
For example, if pilot frequency intensity is higher than γ=- 90dBm, redundant cover is difficult to lift radio link quality.According to formula
（9）With（10）Calculate each adjacent area and cover contribution coefficient, obtain result of calculation as shown in table 3.
Table 3
