Fairness-Aware and Energy Efficiency Resource Allocation in Multiuser OFDM Relaying System

Algorithm 1

Resource allocation iteration algorithm for EE maximization.

(1) Initial maximum number of iterations and maximum tolerance .

(2) Set maximum energy efficiency and iteration index .

(3) repeat  Main Loop

(4)  Solve the inner loop problem in (19) for a given and channel

    assignment and power allocation policy

(5)   if    then

(6)    Convergence = true

(7)    return   and

(8)   else

(9)    Set and

(10)    Convergence = false

(11)   end if

(12) until Convergence = true or
