Resumen:
This article discusses possible solutions to mitigate the different types of fainting that occur in a multipath
channel, which will be chosen for a specific scenario Fixed WiMAX system, where the main problem is to
eliminate the ISI with the help of theoretical analysis and then implement optimal solutions, where we only focus
on two solutions to be implemented in a software simulation using basic elements for a wireless communication
system based on an OFDM system, which takes advantage of using the FFT / IFFT, also the data will be
modulated and demodulated in 16QAM and 32QAM, to finally make a comparison between the data sent with
data received at the output of the system, in order to obtain a measurement as is the bit error rate and finally draw
conclusions from our analysis concerned.
