A demonstration of the effects of downsampling (with and without anti-aliasing) on an audio signal, using the built-in handel sample in MATLAB. This project visualizes both time-domain and ...

Inputs are a received signal sampled at 100Hz for 3000 samples and a 50-symbol long complex preamble for correlation. Downconversion: This entails multitplying the input by two oscillators, a sin and ...
