Statistics are collected for each network user, including signal bandwidth (BW), required receive power (RRP) for decoding a user signal, and available transmit margin (ATM). Users are ordered by BW from greatest to smallest. Users with a greatest BW are then ordered by ATM from lowest to highest, and divided into lower half users having lower ATMs, and upper half users having higher ATMs. A two-tier channel plan is defined, and lower half users are assigned to channels in a lower tier. An upper half user is assigned a channel in an upper tier after placing a lower half user in the same channel in the lower tier, if the upper half user's ATM is >(U User RRP+L User RRP). Otherwise, the user is assigned a different channel in the lower tier. The dividing and subsequent steps repeat for any remaining sets of users requiring successively smaller signal bandwidths. |
