Abstract

A fast and simple method evaluates the capacity of OFDM-based radio networks using adaptive modulation and coding. From a mapping of SINR values to achievable data throughput, constant coefficients defining a linear function for the required channel activity of a single user are determined. Subsequently, linear equations for total uplink and downlink channel activity are obtained which allow fast numerical solutions.
