Method and apparatus for interference signal code power and noise variance estimation

摘要

Method and apparatus for interference signal code power noise variance estimation employing a reduced number of samples utilizing the equation 1 ${\widehat{\mathrm{sigma}}}_n^2=T·\sum _{i=1}^{N_{\mathrm{sample}}}it{h_{nit\left(i\right)}⍼}^2,$ where 2 $T=\frac{G·\mathrm{gamma}it\left(r\right)}{N_{\mathrm{sample}}},$ where Nsample=Lchest-Np1.Kmax, where 3 $\mathrm{gamma}it\left(r\right)={\left[1+\left(\frac{1}{r}-1\right)·\ln it\left(1-r\right)\right]}^{-1}$ and where 4 $r=\frac{N_{\mathrm{sample}}}{L_{\mathrm{chest}}}$
