Abstract

In this paper, we proposed the channel assignment scheme for the CDMA(Code Division Multiple Access) cellular system using power allocation concept. Also, the performance of the proposed scheme was analyzed and it was compared with the channel assignment scheme using the fixed power allocation method in the CDMA cellular system. The proposed scheme allocates the power adaptively in according to the traffic loads and the traffic distribution patter of neighbor cells in the forward link. We found that total call blocking probability (P(%uAC10%uB9C8)) is more dependent on blocking probability (P(%uBCA0%uD0C0)) than outage probability (PO) under physical number of channels (Cth) = 30. P(%uAC10%uB9C8)(Call Blocking Probability) is dependent on P(%uBCA0%uD0C0) (Blocking Probability) and PO(Outage Probability) at the same ratio under Cth=32, in which case PTA (blocking probability for the adaptive power allocation) is greater than PTF (blocking probability for the fixed power allocation) about 6%.
