The effect of multipath interference on the performance of packet radios using ALOHA or slotted ALOHA protocols has been investigated previously in which only the success of line‐of‐sight packets are counted in the evaluation of throughput and delay. Possible improvement in performance due to the survival of delay versions of the direct packets in the presence of the capture effect is studied in this paper. The type of signal capture to be considered is the one in which a signal involved in a collision survives if its power level exceeds the sum of the other signals participating in the same collision.
