Using linear programming to allocate resources in communication systems
نویسنده
چکیده
We consider the following communications system: A mobile cellular telephone company would like to serve K users simultaneously. Each user (transmitter) transmits data to the company’s base station (receiver) in the form of bits (0’s and 1’s). By modulating electromagnetic waves of different frequencies, each user’s data can be transmitted on a fixed set of “frequency slots” approved the government. There are N such slots. If two users transmit on the same frequency slot, their signals (electromagnetic waves) will superimpose at the receiver, making recovery of the message too difficult. We avoid this by imposing the following rule.

Mathematical Programming Approach To Allocate Local Or National Resources For Bridge Maintenance Rehabilitation & Replacement Planning (RESEARCH NOTE)
Today’s, the transportation facilities such as terminals, street, bridge, etc, represent the major investment in highway network. Every year tremendous resources should be invested to maintain these facilities. Among them, the Bridge Management System (B.M.S.) has been necessitated by large imbalance between extensive bridge repair and maintenance needs and limited available budget. So the main...
