Youxi Tang · Systems engineering and electronics · 2009
For a distributed wireless system employing adaptive smart antennas,the uplink load factor is analyzed theoretically.Then a theoretic interference estimation model is established and two admission control algorithms are proposed based on interference estimation.The proposed algorithms can use the model to obtain the interference estimation due to new users.The simulation results show these algorithms based on interference estimation can improve the system performance effectively if a proper noise rise threshold is set,and the algorithm can decrease the block probability at the expense of the outage performance.
