Abstract
In order to satisfy people's growing wireless multimedia communication service
needs, collaboration, communication technology emerged. This paper studies the
wireless cooperative communications collaboration strategy. Which is amplified more
mainstream forwarding (AF) and decode forward (DF). This paper analyzes the
different collaboration strategy works, then use MATLAB to simulate the amount of
different SNR AF and DF cooperative communication system BER performance. From
the simulation results can be seen: is to compare different channel conditions, AF, DF,
and compared to the traditional straight edge where shortcomings where the same SNR
different transmission bit error rate and power consumption and other parameters to
judge the merits of a wireless communication system the major parameters of this study
is to use MATLAB software to complete collaborative strategies for different
circumstances and without the collaboration of the communication results of the
simulation, so that it can determine the different communication good or bad way to
deepen their professional knowledge. The research results can provide a wireless
communication system modeling and design provide a theoretical basis.
The main contents of this paper include: wireless cooperative communication
theory; collaborative communication in different collaboration strategy; MATLAB
simulation processes, M collaboration with MATLLAB programming wireless
communication system simulation.
Keywords: Cooperative Communication AF DF BER
