- Abstract
- Adaptive modulation with coding (AMC) is often
employed to enhance the throughput of OFDM based wireless
systems. The AMC mode is usually adjusted according to the
signal to interference ratio (SIR) of the received signal. Most of
conventional schemes use fixed thresholds for the selection of
AMC mode, yielding a large performance variation depending on
the channel characteristics. This paper proposes the use of
adaptive SIR thresholds for the mode selection in response to the
channel condition, providing significant improvement in
throughput performance in a wide range of channel
environments.
