The Capture Effect in Multiaccess Communications - The Rayleigh and Landmobile Satellite Channel -

Kurzfassung

In this paper we investigate the capture phenomenon and its consequences in nonbitsynchronous mobile packet radio networks for BPSK and DPSK modulation. Exact values of the bit error probability for given signal-to-noise ratios of colliding BPSK signals are derived. Packet error rates, which are needed for analysis of slotted random multiple access methods, are gained by simulation. Two kinds of mobile radio channels are considered: the Rayleigh fading channel and the land mobile satellite channel.
