Power capture ALOHA
R.L. Borchardt, TRI T. HA · 2003
The authors investigate the throughput of unslotted ALOHA with power-capture capability. Two types of capture effects are considered, namely created capture and natural capture. The capture probability of a tagged packet is a function of the maximum number of interfering packets that form a stochastic process during the transmission time of a tagged packet. The distribution of the maximum number of interfacing packets can be found from a set of appropriate binary numbers. Four cases are analyzed: ALOHA with two random power levels, ALOHA in a uniform Rayleigh fading channel, ALOHA with two random power levels in a uniform Rayleigh fading channel, and ALOHA-CDMA in a uniform Rayleigh fading channel.>
