Abstract

This letter is concerned with the assessment of channel access mechanisms for
indoor 3G mobile communications systems offering packet based services. One
such service in which the channel access mechanism will have a significant
impact is Voice Over Internet Protocol (VOIP). This letter considers the impact
of two channel allocation schemes for the indoor environment: mobile-controlled
dynamic channel selection (DCS), and basestation-controlled inhibit sense
multiple access (ISMA). It is shown that the DCS scheme is subject to inferior
performance in packet based voice transmission due to a higher degree of front
end clipping which is introduced.
