4. (16 points) Calculate the cochannel interference ratios at MS in the worst case for the forward channel in sectors cellular systems, given N=7, R=3km, and y=2. Show the calculation steps. a) (8 points) In Figure (a) (a three sectors system), calculate the cochannel interference ratio at MS for the forward channel. BS2 is the current BS of MS, while BS, and BS3 are cochannel BSs. b) (8 points) In Figure (b) (a six sectors system), calculate the cochannel interference ratio at MS for the forward channel. MS BSA MS (a) Forward channel interference in 3 sectors. (b) Forward channel interference in 6 sectors. 4.
