Throughput Performance of Adaptive Modulation and Coding Schemes for WPAN Transceiver

摘要

The main benefit brought by the 60 GHz technology is the high data rates, but it opposes some problems such as inter-symbol interference (lSI), path-loss, and time variant link. To improve the link budget, Adaptive Modulation and Coding (AMC) techniques are utilized. The purpose of this paper is to study the influence of AMC on the High Speed Interface Physical layer (HSI PHY) mode of the IEEE 802.1S.3c standard. For this we have created a Simulink model representing the schema of the IEEE 802.1S.3c transceiver with an algorithm which allows adaptation in terms of modulation and coding of the transmitter whatever channel. And for testing, we used a 60 GHz channel model based on a lot of measured data and statistical analysis named Triple-S and Valenzuela (TSV) model, in both Line-Of Sight (LOS) and Non-Line-Of-Sight (NLOS) scenarios, added to an optical fiber link of fixed length.
