A general expression for the capacity of slotted ALOHA under Nakagami fading

A general expression for the channel throughput of slotted ALOHA under Naka gami fading is obtained assuming different fading statistics and unequal av erage power levels for the desired and the interfering packets. The express ion provides a better alternative to the previously reported expressions de rived under similar conditions. With this general expression the effect of the use of modulation and channel coding on the system performance is then studied. It is observed that the inclusion of the deleterious effects like white noise, bit error rate, and the packet length reduces the throughput c ompared to that observed under idealized conditions.
