| Summary: | Wireless communications technology is a vast and
dynamic field of study. As such, high-reconfigurable tool like
software defined radio is crucially needed. Software defined radio
is a set of tool that consists of RF frond-end hardware and
supported software like MATLAB, GNURadio, etc. For
researcher, software defined radio is important to support the
frequently change configurations and requirements of the studied
system in real scenario as the inflicted cost and time consumed to
re-configure the embedded system are significantly high . For
instance, the endless demand for better quality and service of
wireless communications leads to active research in current
technology like OFDM. The way OFDM been implemented is vary
from one application to the other, which required a high
reconfigurable tool for real scenario experimentation and
analysis. Thus, for knowledge enrichment, this paper intends to
study the basic approach of OFDM by providing an insight of the
system in multipath propagation channels. This paper is the first
part of author’s study whereas the simulation was implemented
on GNU platform. The platform was used to model the OFDM
system that based on both FFT and built-in GNURadio blocks,
and the multipath propagation environment using the flat fading
model. The observed signal constellations across the multipath
models are consistent with the theoretical output, shows the
reliability of GNU platform to deliver the OFDM system which
will be used later for real transmission study. |
