Joint delay-power capture in spread-spectrum packet radio networks
Kyungwhoon Cheun, Sunyoung Kim · IEEE Transactions on Communications · 1998
Capture phenomena in slotted ALOHA packet radio networks employing spread-spectrum modulation is considered. Probability of capture with both delay and power capture mechanisms are derived and compared with power- and delay-only capture models. Significant improvements in the capture probability is observed. The improvement over the delay-only capture model increases with decreasing arrival-time randomization overhead.
