N2 - This paper evaluates performance of a conventional medium access protocol, ALOHA when multiple antennas are employed at a receiver. With the price of signal processing at the receivers, parallel transmissions in the same frequency is resolvable, given that channel matrix can be obtained. This whole system can be seen as a Multiple-Input-Multiple-Output (MIMO) system which is known to increase capacity of a wireless system up to M folds where M is the maximum channel matrix rank. The results show that maximum throughput of the system increases linearly with the number of receiving antennas while the associated average collision increases slightly. However, if the traffic intensity remains fixed, average collision diminishes significantly as number of receiving antennas increases.
