The performance of uplink of CDMA cellular systems with large and small scale fading was investigated based on the large system analysis.The intra-cell multiple access interference was firstly analyzed as well as the inter-cell in-terference.Then the signal to interference and noise ratio was deduced
the result of which was only dependent on the cell load
user power and channel coefficient.Finally
the bit error rate
throughput and spectrum efficiency were analyzed
which were confirmed by simulations.The simulation results show that as the cell load increases
the bit error rate in-creases and the throughput decreases.However
