Modulation and rate adaptation algorithms for terahertz channels

We describe a pulse modulation technique where multiple symbols are transmitted in each pulse. The technique is shown to achieve terabit/sec datarates. Subsequently, we examine the problem of rate adaptation which is significant at these frequencies due to the high distance based attenuation. Algorithms are presented to fairly share the channel among multiple users located at different distances from the access point. The research is based on simulations in Matlab and the channel model used is based on our own measurements using a time-domain terahertz system. The channel model is also presented in this paper.
