Abstract :
This paper proposes an improved power control method, changing the target bit energy per noise spectral density (Eb/No) threshold with adaptive up and down step sizes in variable fading environments. We carry out computer simulations and hardware experiments for verification of the method. The new method results in better frame error rate (FER) and Eb/No performance than the existing ones
