Abstract:
|
In this paper, we derive achievable
rates for arbitrary network topologies consisting
of â cheapâ nodes. A node is labeled â cheapâ if its
radio can only operate in TDD mode when transmitting
and receiving in the same frequency band.
Two main results are shown. The first result provides
an achievable rate for the channel with either
continuous alphabet or discrete channel. The
second result provides the achievable rate for the
Gaussian channel with average power constraint.
The two results are applied to the case of Gaussian
relay channel and concatenated channel with
cheap nodes |
