Abstract
One of the hardest issues in all wireless networks (from 2G to 5G) is sharing the communication channel and the common resources between large set of active users in a cell witch is accompanied by dominant impairment; the interference between users, refers to multiple access interference (MAI) that drastically degrades system performances. In this work, we use the MAI variance expression to develop the formula of the Signal to Noise Plus Interference Ratio (SNIR) in a heavily loaded Code Division Multiple Access (CDMA). Hence, we present performance analysis of a Conventional Correlation Receiver CCR by evaluating the instantaneous SNIR and the BER. The impact on the system performances of relevant parameters such the number of active users, the spreading sequence length and the SNR is studied for both synchronous and asynchronous cases.
