Table 1 Comparison of frequency reuse
From: Downlink performance of cell edge using cooperative BS for multicell cellular network
Frequency reuse | SINR | Cell edge channel capacity |
|---|---|---|
Reuse-1 | \( {\mathrm{SINR}}_{\mathrm{reuse}\hbox{-} 1}=\frac{1}{2+3\times {(2)}^{-\alpha }} \) | \( {C}_{\mathrm{reuse}\hbox{-} 1}=1.{ \log}_2\left(1+{\mathrm{SINR}}_{{}_{\mathrm{reuse}\hbox{-} 1}}\right) \) |
Reuse-3 Reuse-7 | \( {\mathrm{SINR}}_{\mathrm{reuse}\hbox{-} 3}=\frac{3}{3\times {(2)}^{-\alpha }+6\times {(2.7)}^{-\alpha }} \) \( {\mathrm{SINR}}_{\mathrm{reuse}\hbox{-} 7}=\frac{7}{(2)^{-\alpha }+4\times {(2.7)}^{-\alpha }} \) | \( {C}_{\mathrm{reuse}\hbox{-} 3}=\left(\frac{1}{3}\right){ \log}_2\left(1+{\mathrm{SINR}}_{{}_{\mathrm{reuse}\hbox{-} 3}}\right) \) \( {C}_{\mathrm{reuse}\hbox{-} 7}=\left(\frac{1}{7}\right){ \log}_2\left(1+{\mathrm{SINR}}_{{}_{\mathrm{reuse}\hbox{-} 7}}\right) \) |
