Comparación entre la modulación Wavelet y modulaciones tradicionales

Abstract:

Current research is facing the challenges of the growing demand for higher data speeds, better quality of service and greater transmission capacity. For this reason, we must implement the Wavelet modulation technique due to the system's robustness against interference. In this article, a comparative analysis of the binary error rate (BER) and the noise ratio (SNR) of the Wavelet modulations of the families will be carried out; Haar, Daubechies type 8 and Coiflets type 5 compared to traditional QPSK and 4-QAM modulation techniques, these parameters will allow us to know which is the most suitable for the digital communication system, thanks to this it was possible to determine that the Wavelets that they have more than 4 moments of compression and noise elimination, such as those of the Daubechies type 8 and Coiflets type 5 families, presenting a lower margin of error compared to traditional 4-QAM modulation, which does not happen with QPSK modulation.
