On the Asymptotic Stable Throughput of Opportunistic Random Access

Asymptotic stable throughput (AST) is the maximum arrival rate a large network can sup- port while keeping queues bounded. We character- ize the maximum AST of random access with dis- tributed channel state information. The result is ap- plied to CDMA networks with matched fllter and lin- ear MMSE (minimum mean square error) receivers. Networks with and without power control are consid- ered. It is shown that power control does not improve AST if the channel support is large enough.
